the corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.

.SH NAME
timer_delete
\(em delete a per-process timer
.SH SYNOPSIS
.LP
.nf
#include <time.h>
.P
int timer_delete(timer_t \fItimerid\fP);
.fi
.SH DESCRIPTION
The
\fItimer_delete\fR()
function deletes the specified timer,
.IR timerid ,
previously created by the
\fItimer_create\fR()
function. If the timer is armed when
\fItimer_delete\fR()
is called, the behavior shall be as if the timer is automatically
disarmed before removal. The disposition of pending signals for the
deleted timer is unspecified.
.P
The behavior is undefined if the value specified by the
.IR timerid
argument to
\fItimer_delete\fR()
does not correspond to a timer ID returned by
\fItimer_create\fR()
but not yet deleted by
\fItimer_delete\fR().
.SH "RETURN VALUE"
If successful, the
\fItimer_delete\fR()
function shall return a value of zero. Otherwise, the function shall
return a value of \-1 and set
.IR errno
to indicate the error.
.SH ERRORS
No errors are defined.
.LP
.IR "The following sections are informative."
.SH EXAMPLES
None.
.SH "APPLICATION USAGE"
None.
.SH RATIONALE
If an implementation detects that the value specified by the
.IR timerid
argument to
\fItimer_delete\fR()
does not correspond to a timer ID returned by
\fItimer_create\fR()
but not yet deleted by
\fItimer_delete\fR(),
it is recommended that the function should fail and report an
.BR [EINVAL] 
error.
.SH "FUTURE DIRECTIONS"
None.
