Function Documentation

o_free()

void o_free

(

void *

ptr

)

Free a block allocated by o_malloc

o_get_alloc_funcs()

void o_get_alloc_funcs	(	o_malloc_t *	malloc_fn,
		o_realloc_t *	realloc_fn,
		o_free_t *	free_fn
	)

Gets the pointer to current memory functions

Parameters

malloc_fn	reference to a pointer to a malloc function
realloc_fn	reference to a pointer to a realloc function
free_fn	reference to a pointer to a free function

o_malloc()

void* o_malloc

(

size_t

size

)

Allocate a memory block

Parameters

size	the size of the block to allocate in memory

Returns

a pointer to the new allocated block

o_realloc()

void* o_realloc	(	void *	ptr,
		size_t	size
	)

Reallocate a memory block

Parameters

ptr	the previous memory block that will be free'd
size	the size of the block to allocate in memory

Returns

a pointer to the new allocated block with a copy of the data previously in ptr

o_set_alloc_funcs()

void o_set_alloc_funcs	(	o_malloc_t	malloc_fn,
		o_realloc_t	realloc_fn,
		o_free_t	free_fn
	)

Updates the memory functions by user-specific ones

Parameters

malloc_fn	a pointer to a malloc function, if NULL, will use current function
realloc_fn	a pointer to a realloc function, if NULL, will use current function
free_fn	a pointer to a free function, if NULL, will use current function
