zx_timer_cancel

NAME

Cancel a timer.

SYNOPSIS

#include <zircon/syscalls.h>

zx_status_t zx_timer_cancel(zx_handle_t handle);

DESCRIPTION

zx_timer_cancel() cancels a pending timer that was started with zx_timer_set().

Upon success the pending timer is canceled and the ZX_TIMER_SIGNALED signal is de-asserted. If a new pending timer is immediately needed rather than calling zx_timer_cancel() first, call zx_timer_set() with the new deadline.

RIGHTS

handle must be of type ZX_OBJ_TYPE_TIMER and have ZX_RIGHT_WRITE.

RETURN VALUE

zx_timer_cancel() returns ZX_OK on success. In the event of failure, a negative error value is returned.

ERRORS

ZX_ERR_BAD_HANDLE handle is not a valid handle.

ZX_ERR_ACCESS_DENIED handle lacks the right ZX_RIGHT_WRITE.

NOTE

Calling this function before zx_timer_set() has no effect.
