cputime, times − cpu time in this process and children

SYNOPSIS

inttimes(long t[4])

doublecputime(void)

DESCRIPTION

­Times fills in the array ­t with the number of milliseconds spent in user code, system calls, child processes in user code, and child processes in system calls.  ­Cputime returns the sum of those same times, converted to seconds.  ­Times returns the real time, in milliseconds used by the process so far. 

These functions read /dev/cputime, opening that file when ­time is first called.
