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 de‐
scribed 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 conditions
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.
