DESCRIPTION

362       For functions that return a pointer of  type  sip_str_t,  sip_str_t  is
363       supplied by:
364
365         typedef struct sip_str {
366              char *sip_str_ptr;
367              int  sip_str_len;
368         }sip_str_t;
369
370
371
372       The sip_str_ptr parameter points to the start of the returned value and
373       sip_str_len supplies the length of the returned value.
374
375
376       For example, given the following request line in a SIP message  sip_msg
377       that is input to sip_get_request_uri_str():
378
379         FROM : <Alice sip:alice@atlanta.com>;tag=1928301774
380
381
382
383       the return is a pointer to sip_str_t with the sip_str_ptr member point‐
384       ing to "A" of Alice and sip_str_len being  set  to  5,  the  length  of
385       Alice.
386
387
388       Access  functions  for  headers  that can have multiple values take the
389       value as the input, while those that can have only one value  take  the
390       SIP message sip_msg as the input.
391
392
393       The  sip_get_contact_display_name(),  sip_get_from_display_name(),  and
394       sip_get_to_display_name() functions will return the  display  name,  if
395       present,  from  the  CONTACT  header  value, FROM and TO header respec‐
396       tively.
397
398
399       The     sip_get_contact_uri_str(),     sip_get_from_uri_str(),      and
400       sip_get_to_uri_str() functions will return the URI string from the CON‐
401       TACT value, FROM and TO header respectively.
402
403
404       The sip_get_from_tag() and sip_get_to_tag() functions will  return  the
405       TAG  parameter  value, if present, from the FROM and TO header, respec‐
406       tively, in the provided SIP message sip_msg.
407
408
409       The sip_get_callid() function will return the value  from  the  CALL-ID
410       header in the provided SIP message sip_msg.
411
412
413       The sip_get_callseq_num() function will return the call sequence number
414       from the CSEQ header in the provided SIP message sip_msg.
415
416
417       The sip_get_callseq_method() function will return the method  from  the
418       CSEQ  header in the provided SIP message sip_msg. The method can be one
419       of the following:
420         INVITE
421         ACK
422         OPTIONS
423         BYE
424         CANCEL
425         REGISTER
