Detailed Description

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
haystackpointer to the buffer to search in
haystack_lenlength limit of the buffer
needlepointer to the pattern we ar searching for
needle_lenlength limit of the needle
Return values
ptrto start of the match; NULL if no match
