函数名称:do_timer_settime
函数原型:static int do_timer_settime(timer_t timer_id, int tmr_flags, struct itimerspec64 *new_spec64, struct itimerspec64 *old_spec64)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
timer_t | timer_id | |
int | tmr_flags | |
struct itimerspec64 * | new_spec64 | |
struct itimerspec64 * | old_spec64 |
883 | error等于0 |
885 | 如果非Returns true if the timespec64 is norm, false if denorm:或非Returns true if the timespec64 is norm, false if denorm:则返回:负EINVAL |
889 | 如果old_spec64则memset(old_spec64, 0, old_spec64的长度) |
892 | timr等于lock_timer(timer_id, & flags) |
893 | retry : |
898 | 如果WARN_ON_ONCE(!kc || !timer_set)则error等于负EINVAL |
900 | 否则error等于timer_set(timr, tmr_flags, new_spec64, old_spec64) |
903 | 如果error恒等于SPDX-License-Identifier: GPL-2.0 则 |
905 | old_spec64 = NULL |
908 | 转到:retry |
910 | unlock_timer(timr, flags) |
912 | 返回:error |
