      2 .SH NAME
      3 clock - determine processor time
      4 .SH SYNOPSIS
      5 #include <time.h>
      6 
      7 clock_t clock(void)
      8 .SH DESCRIPTION

     10 .BR clock ()
     11 function returns an approximation of processor time used by the program.
     12 .SH RETURN VALUE
     13 The value returned is the CPU time used so far as a clock_t.
     14 In order to get the number of seconds used, divide by
     15 .BR CLOCKS_PER_SEC .
     16 If the processor time used is not available or its value cannot
     17 be represented, the function returns the value (clock_t)-1.
