NAME

        allocrdsrec - allocates memory for a rectangle

SYNOPSYS

       #include"rdsnnn.h"
       rdsrec_list ∗allocrdsrec( Size )
         unsigned int Size;

PARAMETER

       Size                Size of the added structure to the rdsrec_list structure.

DESCRIPTION

       Allocates  a  memory block for rdsrec_list structure and an added structure defined by the
       user. Fields contained in the two structures are set to  NULL  for  pointers  and  0L  for
       numbers.

       NOTE: Allocation by heap ( see rdsalloc function ).

RETURN VALUE

       The pointer to the rectangle structure allocated.

ERRORS

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

                 POINTER_STRING (Rectangle) = (char ∗) malloc (strlen ("Alu1")+1);
                 strcpy(POINTER_STRING(Rectangle),"Alu1");
