DESCRIPTION
       The sip_msg_is_request() function returns B_TRUE if sip_msg is a request and B_FALSE otherwise.

       The sip_msg_is_response() function returns B_TRUE if sip_msg is a response and B_FALSE otherwise.

RETURN VALUES
       For functions that return an integer, the return value is the specified value on success and -1 on error.

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

ERRORS
       These functions take a pointer to an integer error as an argument. If the error is non-null, one of the following values is set:

       EINVAL	 The input SIP message sip_msg or the header value is null; or the specified header/header value is deleted.

       EPROTO	 The header value is not present or invalid. The parser could not parse it correctly.

       ENOMEM	 There is an error allocating memory for the return value.

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