Typedef Documentation

ExifMem

typedef struct _ExifMem ExifMem

ExifMem define a memory allocator.

Definition at line 59 of file exif-mem.h.

ExifMemAllocFunc

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 41 of file exif-mem.h.

ExifMemFreeFunc

typedef void(* ExifMemFreeFunc) (void *p)

Free method for ExifMem.

Parameters

[in]

p

the pointer to free

Returns

the freed pointer

Definition at line 56 of file exif-mem.h.

ExifMemReallocFunc

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
