NAME
       times - get process and child process times

SYNOPSIS
DESCRIPTION
       fills the structure pointed to by buffer with time-accounting information.  The structure defined in is as follows:

	      struct tms {
		  clock_t     tms_utime;      /* user time */
		  clock_t     tms_stime;      /* system time */"
		  clock_t     tms_cutime;     /* user time, children */
		  clock_t     tms_cstime;     /* system time, children */
	      };

       This  information comes from the calling process and each of its terminated child processes for which it has executed a or The times are in
       units of 1/seconds, where is processor dependent.  The value of can be queried using the function (see sysconf(2)).

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

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

       is the sum of the and of the child processes.

       is the sum of the and of the child processes.

RETURN VALUE
       Upon successful completion, returns the elapsed real time, in units of 1/of a second, since an arbitrary point in the past (such as  system
       start-up  time).   This point does not change from one invocation of to another.  If fails, (clock_t) -1 is returned and is set to indicate
       the error.

   Remarks
       has a granularity of one tick.  Processes which run less than one tick may not register any value.

ERRORS
       fails if       buffer points to an illegal address.  The reliable detection of this error is implementation dependent.

WARNINGS
       Not all CPU time expended by system processes on behalf of a user process is counted in the system CPU time for that process.
