gnutls-gnutls.html#gnutls-close-request-tgnutls_close_request_t  how);Terminates the current TLS/SSL connection. The connection should
have been initiated using 
gnutls-gnutls.html#gnutls-handshakegnutls_handshake() .
how should be one of GNUTLS_SHUT_RDWR, GNUTLS_SHUT_WR.
In case of GNUTLS_SHUT_RDWR then the TLS connection gets terminated and
further receives and sends will be disallowed. If the return
value is zero you may continue using the connection.
GNUTLS_SHUT_RDWR actually sends an alert containing a close request
and waits for the peer to reply with the same message.
In case of GNUTLS_SHUT_WR then the TLS connection gets terminated and
further sends will be disallowed. In order to reuse the connection
you should wait for an EOF from the peer.
GNUTLS_SHUT_WR sends an alert containing a close request.
Note that not all implementations will properly terminate a TLS connection.
Some of them, usually for performance reasons, will terminate only the 
underlying transport layer, thus causing a transmission error to the peer.
This error cannot be distinguished from a malicious party prematurely terminating
the session, thus this behavior is not recommended.
This function may also return GNUTLS_E_AGAIN or GNUTLS_E_INTERRUPTED; cf.
gnutls-gnutls.html#gnutls-record-get-directiongnutls_record_get_direction() .

Returns : gnutls_handshake ()
int         gnutls_handshake                ( gnutls-gnutls.html#gnutls-session-tgnutls_session_t  session);This function does the handshake of the TLS/SSL protocol,
and initializes the TLS connection. 
This function will fail if any problem is encountered,
and will return a negative error code. In case of a client,
if the client has asked to resume a session, but the server couldn't, 
then a full handshake will be performed.
The non-fatal errors such as GNUTLS_E_AGAIN and GNUTLS_E_INTERRUPTED
interrupt the handshake procedure, which should be later be resumed.
Call this function again, until it returns 0; cf.
gnutls-gnutls.html#gnutls-record-get-directiongnutls_record_get_direction()  and gnutls-gnutls.html#gnutls-error-is-fatalgnutls_error_is_fatal() .
If this function is called by a server after a rehandshake request then
GNUTLS_E_GOT_APPLICATION_DATA or GNUTLS_E_WARNING_ALERT_RECEIVED 
may be returned. Note that these are non fatal errors, only in the
specific case of a rehandshake. Their meaning is that the client
rejected the rehandshake request.

int         gnutls_rehandshake              ( gnutls-gnutls.html#gnutls-session-tgnutls_session_t  session);This function will renegotiate security parameters with the
client. This should only be called in case of a server.
This message informs the peer that we want to renegotiate
parameters (perform a handshake).
If this function succeeds (returns 0), you must call
the 
gnutls-gnutls.html#gnutls-handshakegnutls_handshake()  function in order to negotiate
the new parameters.
If the client does not wish to renegotiate parameters he
will should with an alert message, thus the return code will be
GNUTLS_E_WARNING_ALERT_RECEIVED and the alert will be
GNUTLS_A_NO_RENEGOTIATION. A client may also choose to ignore
this message.

function should be called if GNUTLS_E_WARNING_ALERT_RECEIVED or
GNUTLS_E_FATAL_ALERT_RECEIVED has been returned by a gnutls
function.  The peer may send alerts if he thinks some things were
not right. Check gnutls.h for the available alert descriptions.

him of something important (eg. his Certificate could not be verified).
If the alert level is Fatal then the peer is expected to close the
connection, otherwise he may ignore the alert and continue.
The error code of the underlying record send function will be returned,
so you may also receive GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN as well.

Sends an alert to the peer depending on the error code returned by a gnutls
function. This function will call 
gnutls-gnutls.html#gnutls-error-to-alertgnutls_error_to_alert()  to determine
the appropriate alert to send.
This function may also return GNUTLS_E_AGAIN, or GNUTLS_E_INTERRUPTED.
If the return value is GNUTLS_E_INVALID_REQUEST, then no alert has
been sent to the peer.

of the specified certificate type.
gnutls_error_is_fatal ()
int         gnutls_error_is_fatal           (int error);If a function returns a negative value you may feed that value
to this function to see if it is fatal. Returns 1 for a fatal 
error 0 otherwise. However you may want to check the
error code manually, since some non-fatal errors to the protocol
may be fatal for you (your program).
This is only useful if you are dealing with errors from the
record layer or the handshake layer.
error :  is an error returned by a gnutls function. Error should be a negative value.
Returns : gnutls_error_to_alert ()
int         gnutls_error_to_alert           (int err,
                                             int *level);
err :  is a negative integer
level :  the alert level will be stored there
Returns : an alert depending on the error code returned by a gnutls
function. All alerts sent by this function should be considered fatal.
The only exception is when err == GNUTLS_E_REHANDSHAKE, where a warning 
alert should be sent to the peer indicating that no renegotiation will 
be performed.
If the return value is GNUTLS_E_INVALID_REQUEST, then there was no
mapping to an alert.
gnutls_perror ()
../gss/gss-ext.html#voidvoid         gnutls_perror                   (int error);This function is like 
perror(). The only difference is that it accepts an 
error number returned by a gnutls function.
error :  is an error returned by a gnutls function. Error is always a negative value.
gnutls_strerror ()
const char* gnutls_strerror                 (int error);This function is similar to 
strerror(). Differences: it accepts an error
number returned by a gnutls function; In case of an unknown error
a descriptive string is sent instead of NULL.
error :  is an error returned by a gnutls function. Error is always a negative value.
Returns : gnutls_handshake_set_private_extensions ()

                                             int allow);
This function will enable or disable the use of private
cipher suites (the ones that start with 0xFF). By default 
or if 
allow is 0 then these cipher suites will not be
advertized nor used.
Unless this function is called with the option to allow (1), then
no compression algorithms, like LZO. That is because these algorithms
are not yet defined in any RFC or even internet draft.
Enabling the private ciphersuites when talking to other than gnutls
servers and clients may cause interoperability problems.

session :  is a gnutls-gnutls.html#gnutls-session-tgnutls_session_t  structure.
Returns : the last handshake message sent. This function is only useful
to check where the last performed handshake failed. If the previous handshake
succeed or was not performed at all then no meaningful value will be returned.
Check gnutls.h for the available handshake descriptions.

succeed or was not performed at all then no meaningful value will be returned.
Check gnutls.h for the available handshake descriptions.
gnutls_record_send ()
ssize_t     gnutls_record_send              ( gnutls-gnutls.html#gnutls-session-tgnutls_session_t  session,

                                             size_t sizeofdata);
This function has the similar semantics with 
send(). The only
difference is that is accepts a GNUTLS session, and uses different
error codes.
If the EINTR is returned by the internal push function (the
default is 
send()} then GNUTLS_E_INTERRUPTED will be returned. If
GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN is returned, you must
call this function again, with the same parameters; alternatively
you could provide a 
NULL pointer for data, and 0 for
size. cf. 
gnutls-gnutls.html#gnutls-record-get-directiongnutls_record_get_direction() .
session :  is a gnutls-gnutls.html#gnutls-session-tgnutls_session_t  structure.
data :  contains the data to send
sizeofdata :  is the length of the data
Returns : the number of bytes sent, or a negative error code. The
number of bytes sent might be less than 
sizeofdata. The maximum
number of bytes this function can send in a single call depends on
the negotiated maximum record size.
gnutls_record_recv ()
ssize_t     gnutls_record_recv              ( gnutls-gnutls.html#gnutls-session-tgnutls_session_t  session,

                                             size_t sizeofdata);
This function has the similar semantics with 
recv(). The only
difference is that is accepts a GNUTLS session, and uses different
error codes.
In the special case that a server requests a renegotiation, the
client may receive an error code of GNUTLS_E_REHANDSHAKE.  This
message may be simply ignored, replied with an alert containing
NO_RENEGOTIATION, or replied with a new handshake, depending on
the client's will.
If EINTR is returned by the internal push function (the default is
code{recv()}) then GNUTLS_E_INTERRUPTED will be returned. If
GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN is returned, you must call
this function again, with the same parameters; alternatively you
could provide a NULL pointer for data, and 0 for
size. cf. 
code{ gnutls-gnutls.html#gnutls-record-get-directiongnutls_record_get_direction() }.
A server may also receive GNUTLS_E_REHANDSHAKE when a client has
initiated a handshake. In that case the server can only initiate a
handshake or terminate the connection.
session :  is a gnutls-gnutls.html#gnutls-session-tgnutls_session_t  structure.
data :  the buffer that the data will be read into
sizeofdata :  the number of requested bytes
Returns : the number of bytes received and zero on EOF.  A negative
error code is returned in case of an error.  The number of bytes
received might be less than 
code{count}.

gnutls_record_get_direction ()
int         gnutls_record_get_direction     ( gnutls-gnutls.html#gnutls-session-tgnutls_session_t  session);This function provides information about the internals of the record
protocol and is only useful if a prior gnutls function call (e.g.
gnutls-gnutls.html#gnutls-handshakegnutls_handshake() ) was interrupted for some reason, that is, if a function
returned GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN. In such a case, you might
want to call 
select() or poll() before calling the interrupted gnutls
function again. To tell you whether a file descriptor should be selected
for either reading or writing, 
gnutls-gnutls.html#gnutls-record-get-directiongnutls_record_get_direction()  returns 0 if
the interrupted function was trying to read data, and 1 if it was trying to
write data.

                                             size_t size);
This function sets the maximum record packet size in this connection.
This property can only be set to clients. The server may
choose not to accept the requested size.
Acceptable values are 512(=2^9), 1024(=2^10), 2048(=2^11) and 4096(=2^12).
session :  is a gnutls-gnutls.html#gnutls-session-tgnutls_session_t  structure.
size :  is the new size
Returns : 0 on success. The requested record size does
get in effect immediately only while sending data. The receive
part will take effect after a successful handshake.
This function uses a TLS extension called 'max record size'.
Not all TLS implementations use or even understand this extension.
gnutls_record_check_pending ()
size_t      gnutls_record_check_pending     ( gnutls-gnutls.html#gnutls-session-tgnutls_session_t  session);This function checks if there are any data to receive
in the gnutls buffers. Returns the size of that data or 0.
Notice that you may also use 
select() to check for data in
a TCP connection, instead of this function.
(gnutls leaves some data in the tcp buffer in order for select
to work).

This function is to be used by clients that want to inform 
(via a TLS extension mechanism) the server of the name they
connected to. This should be used by clients that connect
to servers that do virtual hosting.
The value of 
name depends on the ind type. In case of GNUTLS_NAME_DNS,
an ASCII or UTF-8 null terminated string, without the trailing dot, is expected. 
IPv4 or IPv6 addresses are not permitted.

This function will allow you to get the name indication (if any),
a client has sent. The name indication may be any of the enumeration
gnutls_server_name_type_t.
If 
type is GNUTLS_NAME_DNS, then this function is to be used by servers
that support virtual hosting, and the data will be a null terminated UTF-8 string.
If 
data has not enough size to hold the server name GNUTLS_E_SHORT_MEMORY_BUFFER
is returned, and 
data_length will hold the required size.
index is used to retrieve more than one server names (if sent by the client).
The first server name has an index of 0, the second 1 and so on. If no name with the given

are used by gnutls, to allocate both sensitive and not sensitive data.
This function is provided to set the memory allocation functions to
something other than the defaults (ie the gcrypt allocation functions). 
This function must be called before 
gnutls-gnutls.html#gnutls-global-initgnutls_global_init()  is called.
alloc_func :  it's the default memory allocation function. Like malloc().
secure_alloc_func :  This is the memory allocation function that will be used for sensitive data.
is_secure_func :  a function that returns 0 if the memory given is not secure. May be NULL.
realloc_func :  A realloc function
free_func :  The function that frees allocated data. Must accept a NULL pointer.
gnutls_malloc
extern gnutls_alloc_function gnutls_malloc;
This function will allocate 's' bytes data, and
return a pointer to memory. This function is supposed
to be used by callbacks.

may also be one of the static parameters defined in extra.h.
In case the callback returned a negative number then gnutls will
assume that the username does not exist.
In order to prevent attackers from guessing valid usernames,
if a user does not exist, g and n values should be filled in
using a random user's parameters. In that case the callback must
return the special value (1).
The callback function will only be called once per handshake.

This function can be used to set a callback to retrieve the username and

The callback's function form is:
int (*callback)(gnutls_session_t, unsigned int times, char** username,
 char** password);
The 
username and password must be allocated using gnutls-gnutls.html#gnutls-mallocgnutls_malloc() .
times will be 0 the first time called, and 1 the second.
username and password should be ASCII strings or UTF-8 strings 
prepared using the "SASLprep" profile of "stringprep".
The callback function will be called once or twice per handshake.
The first time called, is before the ciphersuite is negotiated.
At that time if the callback returns a negative error code,
the callback will be called again if SRP has been
negotiated. This uses a special TLS-SRP idiom in order to avoid
asking the user for SRP password and username if the server does
not support SRP.
The callback should not return a negative error code the second
time called, since the handshake procedure will be aborted.
The callback function should return 0 on success.
-1 indicates an error.

This function sets a callback to be called in order to retrieve the certificate
to be used in the handshake.
The callback's function prototype is:
int (*callback)(gnutls_session_t, const gnutls_datum_t* req_ca_dn, int nreqs, 
gnutls_pk_algorithm_t* pk_algos, int pk_algos_length, gnutls_retr_st* st);
st should contain the certificates and private keys.
req_ca_cert, is only used in X.509 certificates. 
Contains a list with the CA names that the server considers trusted. 
Normally we should send a certificate that is signed
by one of these CAs. These names are DER encoded. To get a more
meaningful value use the function 
gnutls_x509_rdn_get().
pk_algos, contains a list with server's acceptable signature algorithms.
The certificate returned should support the server's given algorithms.
If the callback function is provided then gnutls will call it, in the
handshake, after the certificate request message has been received.
The callback function should set the certificate list to be sent, and
return 0 on success. If no certificate was selected then the number of certificates
should be set to zero. The value (-1) indicates error and the handshake
will be terminated.

This function will return the peer's raw certificate (chain) as 
sent by the peer. These certificates are in raw format (DER encoded 
for X.509). In case of a X.509 then a certificate list may be present. 
The first certificate in the list is the peer's certificate,
following the issuer's certificate, then the issuer's issuer etc.
In case of OpenPGP keys a single key will be returned
in raw format.

This function will try to verify the peer's certificate and return
its status (trusted, invalid etc.).  The value of 
status should
be one or more of the gnutls_certificate_status_t enumerated
elements bitwise or'd. To avoid denial of service attacks some
default upper limits regarding the certificate key size and chain
size are set. To override them use
gnutls-gnutls.html#gnutls-certificate-set-verify-limitsgnutls_certificate_set_verify_limits() .
Note that you must also check the peer's name in order to check if
the verified certificate belongs to the actual peer.
session :  is a gnutls session
status :  is the output of the verification
Returns : a negative error code on error and zero on success.
This is the same as 
gnutls_x509_verify_certificate() and uses the
loaded CAs in the credentials as trusted CAs.
Note that some commonly used X.509 Certificate Authorities are
still using Version 1 certificates.  If you want to accept them,
you need to call 
gnutls-gnutls.html#gnutls-certificate-set-verify-flagsgnutls_certificate_set_verify_flags()  with, e.g.,

This function will try to verify the peer's certificate and return
its status (trusted, invalid etc.).  However you must also check
