.SH NAME
door_revoke \- revoke access to a door descriptor
.SH SYNOPSIS
.LP
.nf
\fBcc\fR \fB-mt\fR [ \fIflag\fR... ] \fIfile\fR... [ \fIlibrary\fR... ]
#include <door.h>

\fBint\fR \fBdoor_revoke\fR(\fBint\fR \fId\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBdoor_revoke()\fR function revokes access to a door descriptor. Door
descriptors are created with  \fBdoor_create\fR(3C). The \fBdoor_revoke()\fR
function performs an implicit call to  \fBclose\fR(2), marking the door
descriptor \fId\fR as invalid.
.sp
.LP
A door descriptor can be revoked only by the process that created it.  Door
invocations that are in progress during a \fBdoor_revoke()\fR invocation are
allowed to complete normally.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBdoor_revoke()\fR returns \fB0\fR. Otherwise,
\fBdoor_revoke()\fR returns \(mi1 and sets \fBerrno\fR to indicate the error.
.SH ERRORS
