DESCRIPTION
For functions that return a pointer of type sip_str_t, sip_str_t is
supplied by:
typedef struct sip_str {
char *sip_str_ptr;
int sip_str_len;
}sip_str_t;
The sip_str_ptr parameter points to the start of the returned value and
sip_str_len supplies the length of the returned value.
For example, given the following request line in a SIP message input to
sip_get_request_uri_str():
INVITE sip:marconi@radio.org SIP/2.0
the return is a pointer to sip_str_t with the sip_str_ptr member point‐
ing to "s" of sip:marconi@radio.org and sip_str_len being set to 21,
the length of sip:marconi@radio.org.
The sip_is_sip_uri() function takes a parsed URI sip_uri and returns
B_TRUE if it is a SIP[S] URI and B_FALSE if it is not. A URI is a
SIP[S] URI if the scheme in the URI is either "sip" or "sips".
The sip_get_uri_user() function takes a parsed URI sip_uri and returns
the value of the "user" component, if present.
The sip_get_uri_password() function takes a parsed URI sip_uri and
returns the value of the "password" component, if present.
The sip_get_uri_host() function takes a parsed URI sip_uri and returns
the value of the "host" component, if present.
The sip_get_uri_port() function takes a parsed URI sip_uri and returns
the value of the "port" component, if present.
The sip_get_uri_params() function takes a parsed URI sip_uri and
returns the list of URI parameters, if present, from a SIP[S] URI.
The sip_get_uri_headers() function takes a parsed URI sip_uri and
returns 'headers' from a SIP[S] URI.
The sip_get_uri_query() function takes a parsed URI sip_uri and returns
the value of the 'query' component, if present.
The sip_get_uri_path() function takes a parsed URI sip_uri and returns
the value of the 'path' component, if present.
The sip_get_uri_regname() function takes a parsed URI sip_uri and
returns the value of the 'regname' component, if present.
The sip_is_uri_teluser() function returns B_TRUE if the user component
is a telephone-subscriber. Otherwise, B_FALSE is returned.
The sip_get_uri_errflags() function returns the error flags from a
parsed URI sip_uri. The returned value is a bitmask with the appropri‐
ate bit set when the parser, sip_parse_uri(), encounters an error. The
following are the possible error values that could be set:
Bit value Error Comments
_______________________________________________________________
0x00000001 SIP_URIERR_SCHEME invalid scheme
0x00000002 SIP_URIERR_USER invalid user name
0x00000004 SIP_URIERR_PASS invalid password
0x00000008 SIP_URIERR_HOST invalid host
0x00000010 SIP_URIERR_PORT invalid port number
0x00000020 SIP_URIERR_PARAM invalid URI parameters
0x00000040 SIP_URIERR_HEADER invalid URI headers
0x00000080 SIP_URIERR_OPAQUE invalid opaque
0x00000100 SIP_URIERR_QUERY invalid query
0x00000200 SIP_URIERR_PATH invalid path
0x00000400 SIP_URIERR_REGNAME invalid reg-name
The sip_uri_errflags_to_str() function takes the error flags from a
parsed URI sip_uri and forms a string with all the error bits that are
set. For example, if SIP_URIERR_PASS and SIP_URIERR_PORT are set in a
parsed URI sip_uri, the sip_uri_errflags_to_str() function returns a
string such as:
"Error(s) in PASSWORD, PORT part(s)"
The caller is responsible for freeing the returned string.
RETURN VALUES
The sip_get_uri_scheme(), sip_get_uri_user(), sip_get_uri_password(),
sip_get_uri_host(), sip_get_uri_params(), sip_get_uri_headers(),
sip_get_uri_opaque(), sip_get_uri_query(), sip_get_uri_path(),
sip_get_uri_regname(), and sip_uri_errflags_to_str() functions return
the requested value on success and NULL on failure.
The sip_get_uri_port() function returns port from the URI or 0 if the
port is not present. The returned port is in host byte order.
The value of errno is not changed by these calls in the event of an
error.
ERRORS
If the error is non-null, the following value is set:
EINVAL
The SIP header value of the SIP message is NULL or there is
no URI.
The input URI is null or the requested URI component is
invalid. The error flag is set for the requested component.
The URI parameters or headers are requested from a non-SIP[S]
URI; or the 'opaque', 'query', 'path', 'reg-name' components
are requested from a SIP[S] URI.
On success, the value of the location pointed to by error is set to 0.
