Function http_find_string_value

This function finds a string in a buffer.

char * http_find_string_value(char * buffer, char * match, int buf_len);

Parameters

buffer

Pointer to the buffer to scan for a match.

match

String to search for.

buf_len

Length of *buffer.

return value

Upon a successful match, a pointer to the beginning of the data following the '=' char is returned. For example, a search for "ResetHits" in a buffer containing "&ResetHits=0" will return a pointer to "0".

This function will look in buffer for a string of the form "match=xx" with one of the following characters preceding the match: &, \0 or \n. This will ensure that a search for "Hits" does not match "ResetHits". The parameter buf_len is the length of the buffer.

This function is useful for processing POST commands received from a web browser.
