Function timerfd_settime [src]

Prototype

 pub fn timerfd_settime( fd: i32, flags: system.TFD.TIMER, new_value: *const system.itimerspec, old_value: ?*system.itimerspec, ) TimerFdSetError!void

Parameters

fd: i32flags: system.TFD.TIMERnew_value: *const system.itimerspecold_value: ?*system.itimerspec

Possible Errors

Canceled

InvalidHandle TimerFdGetError

Unexpected UnexpectedError

The Operating System returned an undocumented error code.

This error is in theory not possible, but it would be better to handle this error than to invoke undefined behavior.

When this error code is observed, it usually means the Zig Standard Library needs a small patch to add the error code to the error set for the respective function.
