XmDirectionMatch(library call)					   XmDirectionMatch(library call)

NAME
       XmDirectionMatch -- A function that checks for a specified direction component

SYNOPSIS
       #include <Xm/Xm.h>
       Boolean XmDirectionMatch (d1, d2)
	       XmDirection     d1;
	       XmDirection     d2;
       (void)

DESCRIPTION
       XmDirectionMatch  compares  two	XmDirection values.  The function returns a Boolean value
       depending on whether or not the two input values "match."  The simplest match is  when  d1
       and  d2 are identical.  However, other matches are possible.  XmDirectionMatch attempts to
       compare specified bits only; nonspecified bits automatically match.

       For example, suppose that d1 equals XmTOP_TO_BOTTOM_RIGHT_TO_LEFT. In this case, the func-
       tion will return True if d2 equals either XmRIGHT_TO_LEFT or XmTOP_TO_BOTTOM. However, the
       function  will  return  False   if   d2	 equals   XmTOP_TO_BOTTOM_LEFT_TO_RIGHT,   XmBOT-
       TOM_TO_TOP_RIGHT_TO_LEFT, or XmBOTTOM_TO_TOP_LEFT_TO_RIGHT.

       Note  that direction can be thought of as having three components, a horizontal component,
       a vertical component, and the precedence among them. This means that in	addition  to  the
       previously  mentioned  directions,  the	function  will	still  return  False if d1 equals
       XmTOP_TO_BOTTOM_RIGHT_TO_LEFT and d2 equals XmRIGHT_TO_LEFT_TOP_TO_BOTTOM.

       d1	 Specifies an XmDirection value.

       d2	 Specifies an XmDirection value.

RETURN VALUES
       Returns True if d1 "matches" d2; otherwise, returns False.
