41 For functions that return a pointer of type \fBsip_str_t\fR, \fBsip_str_t\fR is
46 typedef struct sip_str {
55 The \fIsip_str_ptr\fR parameter points to the start of the returned value and
56 \fIsip_str_len\fR supplies the length of the returned value.
59 For example, given the following request line in a \fBSIP\fR message
60 \fIsip_msg\fR that is input to \fBsip_get_request_uri_str()\fR:
64 FROM : <Alice sip:alice@atlanta.com>;tag=1928301774
70 the return is a pointer to \fIsip_str_t\fR with the \fIsip_str_ptr\fR member
71 pointing to "\fBA\fR" of \fBAlice\fR and \fIsip_str_len\fR being set to
72 \fB5\fR, the length of \fBAlice\fR.
75 Access functions for headers that can have multiple values take the value as
76 the input, while those that can have only one value take the \fBSIP\fR message
77 \fIsip_msg\fR as the input.
80 The \fBsip_get_request_method()\fR function will return the \fBSIP\fR method
81 from the request line in the \fBSIP\fR message \fIsip_msg\fR. The method can
82 be one of the following:
133 The \fBsip_get_response_code()\fR function will return the response code
134 \fIresponse\fR from the request line in the \fBSIP\fR message \fIsip_msg\fR.
137 The \fBsip_get_respose_phrase()\fR function will return the response phrase
138 \fIresponse\fR from the request line in the \fBSIP\fR message \fIsip_msg\fR.
141 The \fBsip_get_sip_version()\fR function will return the version of the
142 \fBSIP\fR protocol from the request or the response line in the \fBSIP\fR
143 message \fIsip_msg\fR.
147 For functions that return a pointer to \fIsip_str_t\fR, the return value is the
148 specified value on success or \fBNULL\fR in case of error. For functions that
149 return an integer, the return value is the specified value on success and
153 The value of \fBerrno\fR is not changed by these calls in the event of an
158 These functions take a pointer to an integer \fIerror\fR as an argument. If the
159 error is non-null, one of the following values is set:
166 The input \fBSIP\fR message \fIsip_msg\fR or the header value is null; or the
167 specified header/header value is deleted.
176 The header value is not present or invalid. The parser could not parse it
186 There is an error allocating memory for the return value.
191 On success, the value of the location pointed to by \fIerror\fR is set to
