String BLOCXX_NAMESPACE::FileSystem::Path::dirname

(

const String &

filename

)

Take a string that contains a pathname, and return a string that is a pathname of the parent directory of that file.

Trailing '/' characters in the path are not counted as part of the path. If path does not contain a '/', then dirname() shall return the string ".". If path an empty string, dirname() shall return the string ".".

Parameters:

filename

The file pathname

Returns:

The pathname of the parent directory of filename.

String BLOCXX_NAMESPACE::FileSystem::Path::getCurrentWorkingDirectory

(

)

Get the process's current working directory.

Calls to chdir() or fchdir() will modify this. Multi-threaded applications must exercise caution changing the current working directory.

Exceptions:

FileSystemException,:

ENOENT-The current working directory has been unlinked.

String BLOCXX_NAMESPACE::FileSystem::Path::realPath

(

const String &

path

)

Convert path to the canonicalized absolute pathname by expanding all symbolic links and resolving references to /.

/, /../ and extra / characters. If path is relative, it will be interpreted as relative to the current working directory. This function is similar to the SuSv3 function, however it's easier to use and thread safe.

Parameters:

path

The path to canonicalize.

Returns:

The canonicalized version of path.

Exceptions:

FileSystemException

EACCESS, EIO, ELOOP, ENOENT, ENOTDIR
