Function Documentation

regmatch_t regfind	(	const char *	from,
		const char *	exp
	)

Searches for a regular expression in the given string.

Parameters:

	from	the source string
	exp	the regular expression

Returns:

a struct with a begin and end fields

int regfind_count	(	const char *	from,
		const char *	exp,
		int	offset
	)

Searches for a regular expression in the given string, returning the number of occurrences.

Parameters:

offset

if we want to count "baab" and the last b must be used to form another match we can say to go back offset characters after each match. so passing offset = 1 "baabaab" counts 2 instead of 1.

Returns:

the number of occurrences of exp in from

regoff_t regfind_end	(	const char *	from,

regoff_t regfind_start	(	const char *	from,
