PROLOG

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

NAME

12       timer_delete — delete a per-process timer
13

SYNOPSIS

15       #include <time.h>
16
17       int timer_delete(timer_t timerid);
18

DESCRIPTION

20       The timer_delete() function deletes the specified timer, timerid,  pre‐
21       viously  created  by the timer_create() function. If the timer is armed
22       when timer_delete() is called, the behavior shall be as if the timer is
23       automatically  disarmed before removal. The disposition of pending sig‐
24       nals for the deleted timer is unspecified.
25
26       The behavior is undefined if the value specified by the  timerid  argu‐
27       ment  to  timer_delete()  does not correspond to a timer ID returned by
28       timer_create() but not yet deleted by timer_delete().
29

RETURN VALUE

31       If successful, the timer_delete() function  shall  return  a  value  of
32       zero.  Otherwise, the function shall return a value of -1 and set errno
33       to indicate the error.
34

ERRORS

APPLICATION USAGE

45

RATIONALE

47       If an implementation detects that the value specified  by  the  timerid
48       argument  to  timer_delete() does not correspond to a timer ID returned
49       by timer_create() but not yet deleted by timer_delete(), it  is  recom‐
50       mended that the function should fail and report an [EINVAL] error.
51

FUTURE DIRECTIONS

53       None.
