Function Documentation

BasicSearch()

uint8_t* BasicSearch	(	const uint8_t *	haystack,
		uint32_t	haystack_len,
		const uint8_t *	needle,
		uint16_t	needle_len
	)

Basic search improved. Limits are better handled, so it doesn't start searches that wont fit in the remaining buffer.

Parameters

haystack	pointer to the buffer to search in
haystack_len	length limit of the buffer
needle	pointer to the pattern we ar searching for
needle_len	length limit of the needle

Return values

ptr	to start of the match; NULL if no match

	)

Basic search case less.

Parameters
