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 pointing 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 appropriate 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.
