Module _static_modules._system
- Description
Low-level module that embodies common operating system calls, making them available to the Pike programmer.
- Note
You typically do not want to access this module directly. Use the System module instead.

CPU_TIME_IMPLEMENTATION
constantstring_static_modules._system.CPU_TIME_IMPLEMENTATION- Description
This string constant identifies the internal interface used to get the CPU time. It is an implementation detail - see rusage.c for possible values and their meanings.

CPU_TIME_IS_THREAD_LOCAL
constantstring_static_modules._system.CPU_TIME_IS_THREAD_LOCAL- Description
This string constant tells whether or not the CPU time, returned by e.g. gethrvtime, is thread local or not. The value is "yes" if it is and "no" if it isn't. The value is also "no" if there is no thread support.

CPU_TIME_RESOLUTION
constantint_static_modules._system.CPU_TIME_RESOLUTION- Description
The resolution of the CPU time, returned by e.g. gethrvtime, in nanoseconds. It is
-1if the resolution isn't known.- See also

ITIMER_PROF
constant_static_modules._system.ITIMER_PROF- Description
Identifier for a timer that decrements both when the process is executing and when the system is executing on behalf of the process.

- Constant
ITIMER_REAL
constant_static_modules._system.ITIMER_REAL- Description
Identifier for a timer that decrements in real time.
- See also
- Constant
ITIMER_VIRTUAL
constant_static_modules._system.ITIMER_VIRTUAL- Description
Identifier for a timer that decrements only when the process is executing.

- Constant
REAL_TIME_IMPLEMENTATION
constantstring_static_modules._system.REAL_TIME_IMPLEMENTATION- Description
This string constant identifies the internal interface used to get the high resolution real time. It is an implementation detail - see rusage.c for possible values and their meanings.

- Constant
REAL_TIME_IS_MONOTONIC
constantstring_static_modules._system.REAL_TIME_IS_MONOTONIC- Description
This string constant tells whether or not the high resolution real time returned by gethrtime, is monotonic or not. The value is "yes" if it is and "no" if it isn't.
Monotonic time is not affected by clock adjustments that might happen to keep the calendaric clock in synch. It's therefore more suited to measure time intervals in programs.
