NAME

       allocrdswin - allocates window's table

SYNOPSYS

       #include "rwinnn.h"
        rdswin_list ∗allocrdswin( Number )
           unsigned int Number;

PARAMETER

       Number              Number of windows contained in the window's table.

DESCRIPTION

       The  allocrdswin  allocates  a  window's  table. The number of windows is specified by the
       parameter ´Number´ of the function. To determine the size of the parameter  ´Number´,  the
       user  has  to multiplicate width by height of his table in number of windows. Each item of
       the table is a pointer to a rdswin_list structure  which  contains  rectangles  sorted  by
       layer (see librwi).

RETURN VALUE

       The pointer to the table is returned.

ERRORS

       "Rds202: rdsalloc error, can't continue !"
              it's impossible to allocate the memory size for the table

EXAMPLE

               #include "mutnnn.h"
               #include "rdsnnn.h"
               #include "rwinnn.h"
               #include "rtlnnn.h"
               main()
                 {
                   rdswindow ∗RdsWindow;
                   RdsWindow = allocrdswindow();
                   RdsWindow->XMIN = -200;
                   RdsWindow->YMIN = -200;
                   RdsWindow->XMAX =  200;
                   RdsWindow->YMAX =  200;
                   RdsWindow->DX   =  4;
                   RdsWindow->DY   =  4;
                   RdsWindow->SIDE =  100;
                   RdsWindow->SIZE =  RdsWindow->DX ∗ RdsWindow->DY ;
                   RdsWindow->WINTAB = allocrdswin( RdsWindow->SIZE );
                   . . .
                 }
