NAME


sdp_delete_all_field, sdp_delete_all_media_field - delete all SDP fields

SYNOPSIS


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

int sdp_delete_all_field(sdp_session_t *session,
const char field);


int sdp_delete_all_media_field(sdp_media_t *media,
const char field);


DESCRIPTION


The sdp_delete_all_field() function deletes all the occurrences of the
specified SDP field from the session structure. For example, if the
session structure has 3 bandwidth (b=) fields, then when this function is
called with SDP_BANDWIDTH_FIELD, all the three bandwidth fields are
deleted from the session structure.


The sdp_delete_all_media_field() function deletes all the occurrences of
the specified SDP field from the specified media structure. For example,
if the caller wants to delete all the attribute fields in a media
structure, calling this function with SDP_ATTRIBUTE_FIELD argument would
delete all the attribute fields in the media structure.

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 session or media argument is NULL or the field type is
unknown.
