NAME
       sip_get_header_value, sip_get_next_value - get a SIP header value

SYNOPSIS
       cc [ flag ... ] file ... -lsip [ library ... ]
       #include <sip.h>

       const struct sip_value *sip_get_header_value
	    (const struct sip_header *sip_header, int *error);

       const struct sip_value *sip_get_next_value
	    (sip_header_value_t old_value, int *error);

DESCRIPTION
       The sip_get_header_value() function returns the first valid value from SIP header sip_header.

       The sip_get_next_value() function returns the next valid value following the SIP value old_value.

RETURN VALUES
       These functions return the queried value on success and NULL on failure.

       The value of errno is not changed by these calls in the event of an error.

ERRORS
       If the error is non-null, one of the following values is set:

       EINVAL	 If any of the required input is NULL or if the specified SIP header value is marked deleted.

       EPROTO	 If the returned SIP header value is invalid (i.e. the parser encountered errors when parsing the value).

       On success, the value of the location pointed to by error is set to 0.
