times？
DESCRIPTION
       times() stores the current process times in the struct tms that buf points to.  The struct tms is as defined in <sys/times.h>:

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

       The  tms_utime  field  contains  the CPU time spent executing instructions of the calling process.  The tms_stime field contains the CPU time spent in the system while
       executing tasks on behalf of the calling process.  The tms_cutime field contains the sum of the tms_utime and tms_cutime values for all waited-for terminated children.
       The tms_cstime field contains the sum of the tms_stime and tms_cstime values for all waited-for terminated children.

       Times for terminated children (and their descendants) are added in at the moment wait(2) or waitpid(2) returns their process ID.  In particular, times of grandchildren
       that the children did not wait for are never seen.

       All times reported are in clock ticks.
