.TH FDETACH 3C "Jul 24, 2002"
.SH NAME
fdetach \- detach a name from a STREAMS-based file descriptor
.SH SYNOPSIS
.LP
.nf
#include <stropts.h>

\fBint\fR \fBfdetach\fR(\fBconst char *\fR\fIpath\fR);
.fi

.SH DESCRIPTION
.sp
.LP
The \fBfdetach()\fR function detaches a STREAMS-based file from the file to
which it was attached by a previous call to \fBfattach\fR(3C). The \fIpath\fR
argument points to the pathname of the attached \fBSTREAMS\fR file. The process
must have appropriate privileges or be the owner of the file. A successful call
to \fBfdetach()\fR causes all pathnames that named the attached \fBSTREAMS\fR
file to again name the file to which the \fBSTREAMS\fR file was attached.  All
subsequent operations on \fIpath\fR will operate on the underlying file and not
on the \fBSTREAMS\fR file.
.sp
.LP
All open file descriptions established while the \fBSTREAMS\fR file was
attached to the file referenced by \fIpath\fR, will still refer to the
\fBSTREAMS\fR file after the \fBfdetach()\fR has taken effect.
.sp
.LP
If there are no open file descriptors or other references to the \fBSTREAMS\fR
file, then a successful call to \fBfdetach()\fR has the same effect as
performing the last \fBclose\fR(2) on the attached file.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBfdetach()\fR returns \fB0\fR. Otherwise, it
returns \fB\(mi1\fR and sets \fBerrno\fR to indicate the error.
.SH ERRORS
.sp
