NAME
       XmSetFontUnit -- A function that sets the font unit value for a display

SYNOPSIS
       #include <Xm/Xm.h>
       void XmSetFontUnit(
       Display * display,
       int font_unit_value);

DESCRIPTION
       XmSetFontUnit  provides	an external function to initialize font unit values. Applications
       may want to specify resolution-independent data based on a  global  font  size.	 See  the
       XmNunitType  resource  description  in  the  reference  pages for XmGadget, XmManager, and
       XmPrimitive for more information on resolution independence.

       This function sets the font units for all screens on the display.

       NOTE: XmSetFontUnit is obsolete and  exists  for  compatibility	with  previous	releases.
       Instead	of  using  this  function,  provide  initial  values  or call XtSetValues for the
       XmScreen resources XmNhorizontalFontUnit and XmNverticalFontUnit.

       display	 Defines the display for which this font unit value is to be applied.

       font_unit_value
		 Specifies the value to be used for both horizontal and vertical  font	units  in
		 the conversion calculations.
