+ANSI_SYNOPSIS

+
+TRAD_SYNOPSIS
+	#include <time.h>
+	clock_t clock();
+
+DESCRIPTION
+Calculates the best available approximation of the cumulative amount
+of time used by your program since it started.  To convert the result
+into seconds, divide by the macro <<CLOCKS_PER_SEC>>.
+
+RETURNS
+The amount of processor time used so far by your program, in units
+defined by the machine-dependent macro <<CLOCKS_PER_SEC>>.  If no
+measurement is available, the result is <<-1>>.
+
+PORTABILITY
+ANSI C requires <<clock>> and <<CLOCKS_PER_SEC>>.
+
+Supporting OS subroutine required: <<times>>.
