HPL_timer(3)		     HPL Library Functions		  HPL_timer(3)

NAME
       HPL_timer - Timer facility.

SYNOPSIS
       #include	"hpl.h"

       void HPL_timer( const int I );

DESCRIPTION
       HPL_timer  provides  a  "stopwatch"  functionality  cpu/wall  timer  in
       seconds.	 Up to	64  separate timers can	be functioning at  once.   The
       first  call  starts the timer,  and the second stops it.	 This  routine
       can be disenabled  by calling  HPL_timer_disable(),  so that  calls  to
       the  timer  are ignored.	 This feature can be used to make sure certain
       sections	of code	do not affect timings,	even  if  they	call  routines
       which  have  HPL_timer calls in them. HPL_timer_enable()	will re-enable
       the  timer  functionality.  One	can retrieve  the current value	 of  a
       timer by	calling

       t0 = HPL_timer_inquire( HPL_WALL_TIME | HPL_CPU_TIME, I )

       where   I   is the timer	index in  [0..64).  To	initialize  the	 timer
       functionality, one must have called HPL_timer_boot()  prior to  any  of
       the functions mentioned above.

ARGUMENTS
       I       (global input)	       const int
	       On entry, I specifies the timer to stop/start.
