Description

The sdp_delete_media() function deletes the specified media from the media list. It is similar to deleting a node in a linked list. The function first finds the media that needs to be deleted using sdp_find_media(3COMMPUTIL). The found media is then passed to sdp_delete_media() to delete it. The function frees the memory allocated to media structure after deleting it.

The sdp_delete_attribute() function deletes the specified attribute from the attribute list. It is similar to deleting a node in a linked list. The function first finds the attribute that needs to be deleted using sdp_find_media_rtpmap(3COMMPUTIL) or sdp_find_attribute(3COMMPUTIL). The found attribute is then passed to sdp_delete_attribute() to delete it. The function frees the memory allocated to attribute structure after deleting it.
