Timer

NAME

timer - An object that may be signaled at some point in the future

SYNOPSIS

A timer is used to wait until a specified point in time has occurred or the timer has been canceled.

DESCRIPTION

Like other waitable objects, timers can be waited on via zx_object_wait_one(), zx_object_wait_many(), or zx_object_wait_async().

A given timer can be used over and over.

Once ZX_TIMER_SIGNALED is asserted, it will remain asserted until the timer is canceled (zx_timer_cancel()) or reset (zx_timer_set()).

The typical lifecycle is:

  1. zx_timer_create()
  2. zx_timer_set()
  3. wait for the timer to be signaled
  4. optionally reset and reuse the timer (i.e. goto #2)
  5. zx_handle_close()
