TIMES(2-SVR3)       RISC/os Reference Manual        TIMES(2-SVR3)



NAME
     times - get process and child process times

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

     long times (buffer)
     struct tms *buffer;

DESCRIPTION
     times fills the structure pointed to by buffer with time-
     accounting information.  The following are the contents of
     this structure:

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

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

     tms_cstime is the sum of the tms_stimes and tms_cstimes of
     the child processes.

ERRORS
     [EFAULT]  times will fail if buffer points to an illegal
               address.

SEE ALSO
     exec(2), fork(2), time(2), wait(2).

DIAGNOSTICS
     Upon successful completion, times returns the elapsed real
     time, in clock ticks per second, from an arbitrary point in
     the past (e.g., system start-up time).  This point does not

     fails, a -1 is returned and errno is set to indicate the
     error.
