ClockGettime

Reads the current value of a BSD clock.

Module: BSD

Signature

func ClockGettime(clk_id: int32, tp: *timespec) -> int64;

Parameters

Name	Type	Description
clk_id	int32	Clock to read, such as CLOCK_MONOTONIC.
tp	*timespec	Writable destination for the clock value.

Returns

int64 - 0 on success, or the thunk's raw error result on failure.

The compiler-provided thunk selects the target BSD syscall. Use CLOCK_REALTIME for adjustable wall-clock time and CLOCK_MONOTONIC for elapsed-time measurements.

Example

import BSD::{ ClockGettime, timespec, CLOCK_MONOTONIC };

var now: timespec;
if ClockGettime(CLOCK_MONOTONIC, &now) != 0i64 {
    return 1i32;
}
