.SH NAME
ldi_ev_remove_callbacks \- remove all callbacks for a given callback ID
.SH SYNOPSIS

#include <sys/sunldi.h>

\fBvoid\fR \fBldi_ev_remove_callbacks\fR(\fIldi_ev_callback_id_t id\fR);

\fB\fIldi_ev_callback_id_t id\fR\fR

.sp .6
.RS 4n
An opaque data structure returned on successful calls to
\fBldi_ev_register_callbacks\fR(9F).
.RE

.SH DESCRIPTION
.sp
.LP
The \fBldi_ev_remove_callback()\fR function unregisters any callbacks that were
registered via \fBldi_ev_register_callbacks\fR(9F). Once this function returns,
the callback \fBID\fR is no longer valid.
.sp
.LP
The finalize and notify callbacks exist independently of the \fBLDI\fR handle
and are not automatically removed when the \fBLDI\fR handle is closed. The
layered driver removes these callbacks via \fBldi_ev_remove_callbacks()\fR()
when the callbacks are no longer needed. The \fBLDI\fR framework may panic the
system if the entity registering the callback (a \fBdev_t\fR, \fBdip\fR or
\fBmodule\fR) no longer exists on the system and the callbacks have not been
unregistered.
.SH RETURN VALUES
.sp
.LP
None.
.SH CONTEXT
.sp
.LP
This function can be called from user and kernel contexts only.
