Typedef Documentation

typedef struct _ExifMem ExifMem

ExifMem define a memory allocator

Definition at line 53 of file exif-mem.h.

typedef void*(* ) ExifMemAllocFunc(ExifLong s)

Should work like calloc()

Parameters:

[in]

s

the size of the block to allocate.

Returns:

the allocated memory and initialized.

Definition at line 38 of file exif-mem.h.

typedef void(* ) ExifMemFreeFunc(void *p)

Free method for ExifMem

Parameters:

[in]

p

the pointer to free

Returns:

the freed pointer

Definition at line 50 of file exif-mem.h.

typedef void*(* ) ExifMemReallocFunc(void *p, ExifLong s)

Should work like realloc()

Parameters:

[in]	p	the pointer to reallocate
[in]	s	the size of the reallocated block

Returns:

allocated memory
