twGetGlobal( nHndl )
----------------------------------------------------------------------------
twGetGlobal() returns the current setting of a global variable you
have previously defined. It is most efficient to use this function
in a manifest constant definition in you system header file. Some
common uses are to ensure constancy in system wide colour
definitions and printer queues.
Arguments:
nHndl - 'N' The position in your array of definitions passed with
twInitGlobal() of the handle returned when you add a
global with twAddGlobal().
Return:
Current global variable setting.
Example:
.....
#define NORMALCOLOR twGetGlobal( 3 )
#define NORMALFRAMECOLOR twGetGlobal( 4 )
.....
