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 function 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_BOT-
       TOM_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.
