.Sh DESCRIPTION
Free storage associated with a buffer.
The storage must have been allocated by a GSS-API routine.
In addition to freeing the associated storage,
the routine will zero the length field in the descriptor to which the
buffer parameter refers,
and implementations are encouraged to additionally set the pointer
field in the descriptor to
.Dv NULL .
Any buffer object returned by a GSS-API routine may be passed to
.Fn gss_release_buffer
(even if there is no storage associated with the buffer).
.Sh PARAMETERS
.Bl -tag -width ".It minor_status"
.It minor_status
Mechanism specific status code.
.It buffer
The storage associated with the buffer will be deleted.
The gss_buffer_desc object will not be freed,
but its length field will be zeroed.
