NAME

times − get process times

SYNOPSIS

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

times(buffer)
struct tms ∗buffer;

DESCRIPTION

This interface is obsoleted by getrusage(2). 

Times returns time-accounting information for the current process and for the terminated child processes of the current process.  All times are in centi-seconds. 

This is the structure returned by times:

The children times are the sum of the children’s process times and their children’s times.
