Function Documentation

ws_mempbrk_portable_exec()

const uint8_t * ws_mempbrk_portable_exec	(	const uint8_t *	haystack,
		size_t	haystacklen,
		const ws_mempbrk_pattern *	pattern,
		unsigned char *	found_needle
	)

Search for the first matching byte in a buffer using a precompiled pattern.

Scans the input buffer haystack for the first occurrence of any byte listed in the precompiled pattern. If a match is found, the corresponding needle byte is written to found_needle (if non-NULL), and a pointer to the match location in haystack is returned. If no match is found, returns NULL.

Parameters

haystack	Pointer to the input buffer to search.
haystacklen	Length of the input buffer in bytes.
pattern	Precompiled pattern containing target bytes.
found_needle	Optional output pointer to receive the matched byte.

Returns

Pointer to the first matching byte in haystack, or NULL if none found.
