Module System
- Description
-
This module embodies common operating system calls, making them
available to the Pike programmer.
- Constant
ITIMER_REAL
-
constant System.ITIMER_REAL
- Description
-
Identifier for a timer that decrements in real time.
- See also
-
setitimer , getitimer
- Constant
ITIMER_VIRTUAL
-
constant System.ITIMER_VIRTUAL
- Description
-
Identifier for a timer that decrements only when the
process is executing.
- See also
-
setitimer , getitimer
- Constant
ITIMER_PROF
-
constant 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.

setitimer , getitimer
- Constant
string
-
constant System.string
- 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.

gethrvtime , gauge
- Constant
int
-
constant System.int
- Description
-
The resolution of the CPU time, returned by e.g. gethrvtime , in
nanoseconds. It is -1 if the resolution isn't known.

gethrvtime , gauge
- Constant
string
-
constant System.string
- 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.

gethrvtime , gauge
- Constant
string
-
constant System.string
- 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.

gethrtime
- Constant
int
-
constant System.int
- Description
-
The resolution of the real time returned by gethrtime , in
nanoseconds. It is -1 if the resolution isn't known.

the high resolution real time. It is an implementation detail -
