#### NAME

> timer_delete - delete a per-process timer

#### SYNOPSIS

> ``[CX] #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.

#### SEE ALSO

> timer_create

> XBD <time.h>

#### CHANGE HISTORY

> First released in Issue 5. Included for alignment with the POSIX Realtime Extension.

#### Issue 6

> The timer_delete() function is marked as part of the Timers option.

> The [ENOSYS] error condition has been removed as stubs need not be provided if an implementation does not support the Timers option.

> IEEE Std 1003.1-2001/Cor 2-2004, item XSH/TC2/D6/139 is applied, updating the ERRORS section so that the [EINVAL] error becomes optional.

#### Issue 7

> The timer_delete() function is moved from the Timers option to the Base.

> POSIX.1-2008, Technical Corrigendum 2, XSH/TC2-2008/0369 [659] is applied.
