TIMER_DELETE(3P)        POSIX Programmer's Manual       TIMER_DELETE(3P)

PROLOG

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

NAME

       timer_delete — delete a per-process timer

SYNOPSIS

       #include <time.h>

       int timer_delete(timer_t timerid);

DESCRIPTION

       The timer_delete() function deletes the specified timer, timerid,
       previously created by the timer_create() function. If the timer
       is armed when timer_delete() 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.

       The behavior is undefined if the value specified by the timerid
       argument to timer_delete() does not correspond to a timer ID
       returned by timer_create() but not yet deleted by timer_delete().

RETURN VALUE

       If successful, the timer_delete() function shall return a value
       of zero. Otherwise, the function shall return a value of -1 and
       set errno to indicate the error.

ERRORS

       No errors are defined.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       None.

RATIONALE

       If an implementation detects that the value specified by the
       timerid argument to timer_delete() does not correspond to a timer
       ID returned by timer_create() but not yet deleted by
       timer_delete(), it is recommended that the function should fail
       and report an [EINVAL] error.

FUTURE DIRECTIONS

       None.
