SYNOPSIS


cc [ flag...] file... -lcommputil [ library...]
#include <sdp.h>

int sdp_delete_media(sdp_media_t **l_media, sdp_media_t *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.
