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.

Use libc's memmem if available.

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

		uint32_t	haystack_len,
		const uint8_t *	needle,
		uint16_t	needle_len
	)

Basic search case less.

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
