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 | +-----------------------------+-----------------------------+ |Interface Stability |Committed | +-----------------------------+-----------------------------+ |MT-Level |Safe | +-----------------------------+-----------------------------+ SEE ALSO
