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()

SYSCALLS

  • [zx_timer_create()] - create a timer
  • [zx_timer_set()] - set a timer
  • [zx_timer_cancel()] - cancel a timer
