Macros
#define	LOGMEM(CTX)
#define	LY_ARRAY_CREATE(CTX, ARRAY, SIZE, EACTION)
	Allocate a (sized array) for the specified number of items. If the ARRAY already exists, it is resized (space for SIZE items is added and zeroed). More...
#define	LY_ARRAY_CREATE_GOTO(CTX, ARRAY, SIZE, RET, GOTO)   LY_ARRAY_CREATE(CTX, ARRAY, SIZE, RET = LY_EMEM; goto GOTO)
	Allocate a (sized array) for the specified number of items. If the ARRAY already exists, it is resized (space for SIZE items is added). More...
#define	LY_ARRAY_CREATE_RET(CTX, ARRAY, SIZE, RETVAL)   LY_ARRAY_CREATE(CTX, ARRAY, SIZE, return RETVAL)
	Allocate a (sized array) for the specified number of items. If the ARRAY already exists, it is resized (space for SIZE items is added and zeroed). More...
#define	LY_ARRAY_DECREMENT(ARRAY)   --(*((LY_ARRAY_COUNT_TYPE*)(ARRAY) - 1))
	Decrement the items counter in a (sized array). More...
#define	LY_ARRAY_DECREMENT_FREE(ARRAY)
	Decrement the items counter in a (sized array) and free the whole array in case it was decremented to 0. More...
#define	LY_ARRAY_FREE(ARRAY)   if (ARRAY){free((LY_ARRAY_COUNT_TYPE*)(ARRAY) - 1);}
	Free the space allocated for the (sized array). More...
#define	LY_ARRAY_INCREMENT(ARRAY)   ++(*((LY_ARRAY_COUNT_TYPE*)(ARRAY) - 1))
	Increment the items counter in a (sized array). More...
#define	LY_ARRAY_NEW(CTX, ARRAY, EACTION)
	(Re-)Allocation of a (sized array). More...
#define	LY_ARRAY_NEW_GOTO(CTX, ARRAY, NEW_ITEM, RET, GOTO)
	(Re-)Allocation of a (sized array). More...
#define	LY_ARRAY_NEW_RET(CTX, ARRAY, NEW_ITEM, RETVAL)
	(Re-)Allocation of a (sized array). More...
#define	LY_ARRAY_REMOVE_VALUE(ARRAY, VALUE)
	Remove item from array based on value. More...
#define	LY_LIST_INSERT(LIST, NEW_ITEM, LINKER)
	Insert item into linked list. More...
#define	LY_LIST_NEW(CTX, LIST, NEW_ITEM, LINKER, EACTION)
	Allocate and insert new item into linked list, return in case of error. More...
#define	LY_LIST_NEW_GOTO(CTX, LIST, NEW_ITEM, LINKER, RET, LABEL)   LY_LIST_NEW(CTX, LIST, NEW_ITEM, LINKER, RET = LY_EMEM; goto LABEL)
	Allocate and insert new item into linked list, goto specified label in case of error. More...
#define	LY_LIST_NEW_RET(CTX, LIST, NEW_ITEM, LINKER, RETVAL)   LY_LIST_NEW(CTX, LIST, NEW_ITEM, LINKER, return RETVAL)
	Allocate and insert new item into linked list, return in case of error. More...

Functions
void *	ly_realloc (void *ptr, size_t size)
	Wrapper for realloc() call. The only difference is that if it fails to allocate the requested memory, the original memory is freed as well. More...

Function Documentation

void* ly_realloc	(	void *	ptr,
		size_t	size
	)

Wrapper for realloc() call. The only difference is that if it fails to allocate the requested memory, the original memory is freed as well.

Parameters

[in]	ptr	Memory to reallocate.
[in]	size	New size of the memory block.

Returns

Pointer to the new memory, NULL on error.
