		char *	val,
		size_t *	len
	)

Execute all substitutions on val.

Return values

True	If substituition was made.
False	If no substituition was made.

r->buf points at the resulting buffer with all substitutions done. len points at length of resulting buffer. r->even_buf and r->odd_buf might have been reallocated. r->even_buf_len and r->odd_buf_len might have been changed.

search_protocol_re()

int search_protocol_re	(	std::regex *	re,
		const char *	str
	)
