Procedure

   void wninsd_c ( SpiceDouble     left,
                   SpiceDouble     right,
                   SpiceCell     * window ) 

Abstract

 
   Insert an interval into a double precision window.

Brief_I/O

 
   VARIABLE  I/O  DESCRIPTION 
   --------  ---  -------------------------------------------------- 
   left, 
   right      I   Left, right endpoints of new interval. 
   window    I,O  Input, output window. 
 

Detailed_Input

 
   left, 
   right       are the left and right endpoints of the interval 
               to be inserted. 

   window      on input, is a CSPICE window containing zero or more 
               intervals. 
 
               window must be declared as a double precision
               SpiceCell.

Detailed_Output

 
   window      on output, is the original window following the 
               insertion of the interval from left to right. 
 

Parameters

 
   None. 
 

Exceptions

 
   1) If the input window does not have double precision type,
      the error SPICE(TYPEMISMATCH) is signaled.

   2) If left is greater than right, the error SPICE(BADENDPOINTS) is 
      signaled. 
 
   3) If the insertion of the interval causes an excess of elements, 
      the error SPICE(WINDOWEXCESS) is signaled. 
 

Files

 
   None. 
 

Particulars

 
   This routine inserts the interval from left to right into the 
   input window. If the new interval overlaps any of the intervals 
   in the window, the intervals are merged. Thus, the cardinality 
   of the input window can actually decrease as the result of an 
   insertion. However, because inserting an interval that is 
   disjoint from the other intervals in the window can increase the 
   cardinality of the window, the routine signals an error. 
 
   No other CSPICE unary window routine can increase the number of
   intervals in the input window.

Examples

 
    Let window contain the intervals 
 
       [ 1, 3 ]  [ 7, 11 ]  [ 23, 27 ] 
 
    Then the following series of calls 
 
       wninsd_c ( 5.0,  5.0, &window )                  (1) 
       wninsd_c ( 4.0,  8.0, &window )                  (2) 
       wninsd_c ( 0.0, 30.0, &window )                  (3) 
 
    produces the following series of windows 

       [ 1,  3 ]  [ 5,  5 ]  [  7, 11 ]  [ 23, 27 ]     (1) 
       [ 1,  3 ]  [ 4, 11 ]  [ 23, 27 ]                 (2) 
       [ 0, 30 ]                                        (3)
