Function Documentation

int sip_contact_accept	(	sip_contact_t const *	m,
		sip_accept_contact_t const *	cp,
		unsigned *	return_S,
		unsigned *	return_N,
		int *	return_error
	)

Check if Contact matches by Accept-Contact.

Return values:

	1	if successful
	0	if an error occurs

int sip_prefs_matching	(	char const *	pvalue,
		char const *	nvalue,
		int *	return_parse_error
	)

Check callerprefs.

The function sip_prefs_matching() checks if the given feature values match with each other.

Parameters:

	pvalue	first feature parameter
	nvalue	second feature parameter
	return_parse_error	return-value parameter for error (may be NULL)

Returns:: The function sip_prefs_match() returns 1, if given feature parameters match. The function sip_prefs_match() returns 0, if there is no match or a parse or type error occurred.

If there is a parsing or type error, 0 is returned and return_parse_error is set to -1.
