system-time-monotonic: Simple library for using the system's monotonic clock

[ bsd3, library, system ] [ Propose Tags ]

Simple library for using the system's monotonic clock. This library is geared toward programs that need to run for long periods of time. It does not (necessarily) provide high-resolution timing.

• On Windows, this uses GetTickCount64, but falls back to GetTickCount if it is not available. GetTickCount64 was introduced in Windows Vista and Windows Server 2008. Support for QueryPerformanceCounter is also available, but is not used by default, as it is less accurate in the long run than GetTickCount.

• On Linux, this uses clock_gettime with CLOCK_MONOTONIC.
