 NAME
sdp_delete_media, sdp_delete_attribute - delete the specified media or
attribute from the appropriate list

 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.

 RETURN VALUES

Upon successful completion, these functions return 0. Otherwise, the
appropriate error value is returned. The value of errno is not changed by
these calls in the event of an error.

 ERRORS

These functions will fail if:


EINVAL


The mandatory input parameters are not provided or are NULL.
