NAME

     tpctl -- touch panel calibration utility

SYNOPSIS

     tpctl [-D dispdevname] [-d devname] [-f filename] [-hnuv]

DESCRIPTION

     tpctl is a touch panel calibration utility.  tpctl calibrates a touch panel and saves and restores the calibration parameters into/from a
     parameter database file.

     Available command-line flags are:
     -D dispdevname   Specify display device name.
     -d devname       Specify touch panel device name.
     -f filename      Specify alternate parameter database file name.
     -h 	      Print brief description.
     -n 	      Do not change the parameter database file.
     -u 	      Force calibration.  Without this flag, tpctl won't do calibration if the database file already contains parameters for the
		      touch panel.
     -v 	      Verbose mode.

     You calibrate the touch panel the first time you run tpctl.  If you see a cross cursor on the screen, you should tap the center of the cursor
     to calibrate the touch panel, or you can abort the calibration with the 'ESC' key.  Five cursors will appear on the screen in turn.  Once
     calibration is done, tpctl saves the calibration parameters into the database file and uses the saved parameters to calibrate the touch
     panel.

     You can run tpctl automatically with /etc/rc.d/tpctl.

FILES

     /etc/tpctl.dat  The default calibration parameter database file.  The -f flag may be used to specify an alternate database file name.  tpctl
		     will create an empty database file if it doesn't exist.
     /dev/ttyE0      The default display device, which is used to display the cursor during calibration.  The -D flag may be used to specify an
		     alternate display device name.  The display device must provide the 'hpcfb' interface as defined in
		     /usr/include/dev/hpc/hpcfbio.h.
     /dev/wsmux0     The default touch panel device.  The -d flag may be used to specify an alternate touch panel device name.

SEE ALSO

     rc.conf(5)

BUGS

     tpctl isn't available on all ports because it requires a display device which provides the 'hpcfb' interface.

touch - Sets access and modification time of file

SYNOPSIS

       bool touch (string  $filename, [int  $time = time()], [int  $atime])

DESCRIPTION

	Attempts  to set the access and modification times of the file named in the $filename parameter to the value given in $time. Note that the
       access time is always modified, regardless of the number of parameters.

	If the file does not exist, it will be created.

PARAMETERS

	      o $filename
		- The name of the file being touched.

	      o $time
		- The touch time. If $time is not supplied, the current system time is used.

	      o $atime
		- If present, the access time of the given filename is set to the value of $atime. Otherwise, it is set to the value passed to the
		$time parameter. If neither are present, the current system time is used.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      touch(3) example

	      <?php
	      if (touch($filename)) {
		  echo $filename . ' modification time has been changed to present time';
	      } else {
		  echo 'Sorry, could not change modification time of ' . $filename;
	      }
	      ?>

       Example #2

	      touch(3) using the $time parameter

	      <?php
	      // This is the touch time, we'll set it to one hour in the past.
	      $time = time() - 3600;

	      // Touch the file
	      if (!touch('some_file.txt', $time)) {
		  echo 'Whoops, something went wrong...';
	      } else {
		  echo 'Touched file with success';
	      }
	      ?>

NOTES

       Note

	      Note that time resolution may differ from one file system to another.

       Warning

	       Prior to PHP 5.3.0 it was not possible to change the modification time of a directory with this function under Windows.
