-Brief_I/O

   VARIABLE  I/O  DESCRIPTION 
   --------  ---  -------------------------------------------------- 
   point      I   Input point. 
   window     I   Input window. 

   The function returns SPICETRUE if point is an element of window. 
 
-Detailed_Input

   point       is a point, which may or may not be contained in 
               one of the intervals in window. 

   window      is a CSPICE window containing zero or more intervals. 

               window must be declared as a double precision SpiceCell.
 
-Detailed_Output
 
   The function returns SPICETRUE if the input point is an element of 
   the input window---that is, if 

      a(i)  <  point  <  b(i) 
            -         - 

   for some interval [ a(i), b(i) ] in window---and returns SPICEFALSE 
   otherwise. 
 
-Parameters
 
   None. 
 
-Exceptions
  
   1) If the input window does not have double precision type,
      the error SPICE(TYPEMISMATCH) is signaled.
 
-Files
 
   None. 
 
-Particulars
 
   None. 
 
-Examples
 
   Let a contain the intervals 

      [ 1, 3 ]  [ 7, 11 ]  [ 23, 27 ] 

   Then the following expressions take the value SPICETRUE

      wnelmd_c ( 1.0, &window );
      wnelmd_c ( 9.0, &window );

   and the following expressions take the value SPICEFALSE

      wnelmd_c (  0.0, &window );
      wnelmd_c ( 13.0, &window );
      wnelmd_c ( 29.0, &window );
