Typedef Documentation

typedef struct _ExifMem ExifMem

ExifMem define a memory allocator.

Definition at line 57 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 39 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 54 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
