times(2)                         System Calls                         times(2)



NAME
       times - get process and child process times

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

       clock_t times(struct tms *buffer);

DESCRIPTION
       The  times() function fills the tms structure pointed to by buffer with
       time-accounting   information.   The   tms   structure,   defined    in
       <sys/times.h>, contains the following members:

         clock_t    tms_utime;
         clock_t    tms_stime;
         clock_t    tms_cutime;
         clock_t    tms_cstime;



       All  times  are reported in clock ticks. The specific value for a clock
       tick is defined by the variable CLK_TCK,  found  in  the  header  <lim‐
       its.h>.


       The  times of a terminated child process are included in the tms_cutime
       and tms_cstime members of  the  parent  when  wait(3C)  or  waitpid(3C)
       returns the process ID of this terminated child. If a child process has
       not waited for its children, their times will not be  included  in  its
       times.


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


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


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


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

RETURN VALUES
       Upon  successful  completion, times() returns the elapsed real time, in
       clock ticks, since an arbitrary point in the past (for example,  system
       start-up  time).  This  point  does  not  change from one invocation of
       times() within the process to another. The return  value  may  overflow
       the  possible  range  of type clock_t. If times() fails, (clock_t)−1 is
       returned and errno is set to indicate the error.

ERRORS
       The times() function will fail if:

       EFAULT    The buffer argument points to an illegal address.
