Adding a Repeat Field to the SDP Session Structure

The sdp_add_repeat() function adds the REPEAT (r=) SDP field to the session structure using the values of the interval, duration, and offset parameters. The value of the offset parameter is a string that holds one or more offset values, such as 60 or 60 1d 3h. The value of the time parameter is the pointer to the time structure that the sdp_add_time() function creates.

Return Values: The sdp_add_repeat() function returns 0 when the function completes successfully. When mandatory parameters are not present, the function returns EINVAL. When memory allocation fails, the function returns ENOMEM. The value of errno does not change in the event of an error.
