.TH INOTIFY_RM_WATCH 3C "Sep 17, 2014"
.SH NAME
inotify_rm_watch \- remove a watch from an inotify instance
.SH SYNOPSIS
.LP
.nf
#include <sys/inotify.h>
\fBint\fR \fBinotify_rm_watch\fR(\fBint\fR \fIfd\fR, \fBint\fR \fIwd\fR);
.fi
.SH DESCRIPTION
.sp
.LP
The \fBinotify_rm_watch()\fR function removes the watch specified
by \fIwd\fR from the inotify instance associated with \fIfd\fR.
Removing a watch will induce an \fBIN_IGNORED\fR event; see
\fBinotify\fR(5) for details.
.SH RETURN VALUES
.sp
.LP
Upon succesful completion, \fBinotify_add_watch()\fR returns the
watch descriptor associated with the new watch.
If an error occurs, -1 is returned and errno is set to indicate
the error.
.SH ERRORS
.sp
.LP
\fBinotify_rm_watch()\fR will fail if:
.sp
.ne 2
.na
\fB\fBEBADF\fR\fR
.ad
.RS 10n
The \fIfd\fR argument is not a valid open file descriptor.
.RE
.sp
.ne 2
.na
\fB\fBEINVAL\fR\fR
.ad
.RS 10n
The \fIfd\fR argument does not correspond to an
\fBinotify\fR(5) instance as initialized with
\fBinotify_init\fR(3C) or \fBinotify_init1\fR(3C), or
\fIwd\fR is not a valid watch for the specified inotify
instance.
.RE
.sp
.SH NOTES
.sp
.LP
While the \fBinotify\fR(5) facility is implemented for purposes of
offering compatibility for Linux-borne applications, native
applications may opt to use it instead of (or in addition to) the
\fBPORT_SOURCE_FILE\fR capability of event ports. See
\fBinotify\fR(5) for details and restrictions.
