#include <sdp.h>
int sdp_delete_media(

int sdp_delete_attribute(
sdp_attr_t **l_attr,
sdp_attr_t *attr);
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.
RETURN VALUES

appropriate error value is returned. The value of

changed by these calls in the event of an error.
