clock_getcpuclockid(3c)

Standard C Library Functions                           clock_getcpuclockid(3C)



NAME
       clock_getcpuclockid - access a process CPU-time clock

SYNOPSIS
       #include <time.h>

       int clock_getcpuclockid(pid_t  pid, clockid_t *clock_id);

DESCRIPTION
       The  clock_getcpuclockid()  function  shall  return the clock ID of the
       CPU-time clock  of  the  process  specified  by  pid.  If  the  process
       described  by  pid  exists  and the calling process has permission, the
       clock ID of this clock shall be returned in clock_id. If pid  is  zero,
       the  clock_getcpuclockid()  function  shall  return the clock ID of the
       CPU-time clock of the process making the call in clock_id.  The  condi‐
       tions  under  which  one  process has permission to obtain the CPU-time
       clock ID of other processes are implementation-defined.

RETURN VALUES
       On successful completion, clock_getcpuclockid() shall return 0;  other‐
       wise an error shall be returned to indicate the error

ERRORS
       The clock_getcpuclockid() function will fail if:

       EPERM    The  requesting process does not have permission to access the
                CPU-time clock for the process.



       The clock_getcpuclockid() function may fail if:

       ESRCH    No process can be found corresponding to the process specified
                by pid.
