A collection of utility function for operating on C strings with wmem.

Function Documentation

wmem_compare_int()

WS_DLL_PUBLIC int wmem_compare_int	(	gconstpointer	a,
		gconstpointer	b
	)

Generic GCompareFunc implementations to compare signed/unsigned integer

wmem_memdup()

WS_DLL_PUBLIC void* wmem_memdup	(	wmem_allocator_t *	allocator,
		const void *	source,
		const size_t	size
	)

Copies a block of memory.

Parameters

allocator	The allocator object to use to allocate memory to copy into.
source	The pointer to the memory block to copy.
size	The amount of memory to copy.

Returns

The location of the memory copy or NULL if size is 0.

ws_memmem()

WS_DLL_PUBLIC const uint8_t* ws_memmem	(	const void *	haystack,
		size_t	haystack_len,
		const void *	needle,
		size_t	needle_len
	)

Return the first occurrence of needle in haystack.

Parameters

haystack	The data to search
haystack_len	The length of the search data
needle	The string to look for
needle_len	The length of the search string

Returns

A pointer to the first occurrence of "needle" in "haystack". If "needle" isn't found or is NULL, NULL is returned. If "needle_len" is 0, a pointer to "haystack" is returned.
