times(2)                                                              times(2)


NAME
     times - get process and child process times

SYNOPSIS
     #include <sys/types.h>
     #include <sys/times.h>

     clock_t times(struct tms *buffer);

DESCRIPTION
     times fills the tms structure pointed to by buffer with time-accounting
     information.  The tms structure is defined in <sys/times.h> as follows:

          struct    tms {
               clock_t    tms_utime;
               clock_t    tms_stime;
               clock_t    tms_cutime;
               clock_t    tms_cstime;
          };

     This information comes from the calling process and each of its
     terminated child processes for which it has executed a wait routine.  All
     times are reported in clock ticks.  Clock ticks are a system-dependent
     parameter.  The specific value for an implementation is defined by the
     variable CLK_TCK, found in the include file limits.h.

     tms_utime is the CPU time used while executing instructions in the user
     space of the calling process.

     tms_stime is the CPU time used by the system on behalf of the calling
     process.

     tms_cutime is the sum of the tms_utime and the tms_cutime of the child
     processes.

     tms_cstime is the sum of the tms_stime and the tms_cstime of the child
     processes.

     times fails if:

     EFAULT        buffer points to an illegal address.

DIAGNOSTICS
     Upon successful completion, times returns the elapsed real time, in clock
     ticks, from an arbitrary point in the past (e.g., system start-up time).
     This point does not change from one invocation of times to another.  If
     times fails, a -1 is returned and errno is set to indicate the error.
