.SH DESCRIPTION
.sp
.LP
The \fBsdp_delete_media()\fR 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 \fBsdp_find_media\fR(3COMMPUTIL). The found media is then passed to \fBsdp_delete_media()\fR to delete it. The function frees the memory allocated to media structure after deleting it.
.sp
.LP
The \fBsdp_delete_attribute()\fR 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 \fBsdp_find_media_rtpmap\fR(3COMMPUTIL) or \fBsdp_find_attribute\fR(3COMMPUTIL). The found attribute is then passed to \fBsdp_delete_attribute()\fR to delete it. The function frees the memory allocated to attribute structure after deleting it.
