#include <sdp.h>
int sdp_delete_all_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.
