sdp_delete_media(3COMMPUTIL)		     Communication Protocol Parser Utilities Library Functions		      sdp_delete_media(3COMMPUTIL)

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(3COMM-
       PUTIL).	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.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
