If the process described by \fIpid\fR exists and the calling process has permission, the clock ID of this clock shall be returned in \fIclock_id\fR. If \fIpid\fR is zero, the \fBclock_getcpuclockid()\fR function shall return the clock ID of the CPU-time clock of the process making the call in \fIclock_id\fR. The conditions under which one process has permission to obtain the CPU-time clock ID of other processes are implementation-defined. .SH RETURN VALUES .sp .LP On successful completion, \fBclock_getcpuclockid()\fR shall return 0; otherwise an error shall be returned to indicate the error .SH ERRORS .sp .LP The \fBclock_getcpuclockid()\fR function will fail if: .sp .ne 2 .mk .na \fB\fBEPERM\fR\fR .ad .RS 9n .rt The requesting process does not have permission to access the CPU-time clock for the process. .RE .sp .LP The \fBclock_getcpuclockid()\fR function may fail if: .sp .ne 2 .mk .na \fB\fBESRCH\fR\fR .ad .RS 9n .rt No process can be found corresponding to the process specified by \fIpid\fR. .RE .SH ATTRIBUTES .sp .LP See \fBattributes\fR(7) for descriptions of the following attributes: .sp .TS tab( ) box; cw(2.75i) |cw(2.75i) lw(2.75i) |lw(2.75i) .
