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 argu-
ment 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.
