i don't think you ment array pointer here.

anyway, for your purposes, you might want to consider the following:
(i will have to add that this is kinda off-topic, but i thought it might
be useful. in any case, this sort of C questions would get better
answers in forums such as comp.lang.c.moderated.)

i have a feeling the code below makes a case for using C++ ;-)

/*
 * constants for different kinds of windows
 * for code that might need the information
 */

#define WT_WINDOW 0
#define WT_BUTTON 1
/* etc */

typedef struct TAG_BUTTON_DATA
{
   int    x1;
   int    y1;
   int    x2;
   int    y2;
   int    state;
   int    frame;
} BUTTON_DATA;

typedef struct TAG_WINDOW_DATA
{
 char* title;
} WINDOW_DATA;

typedef union TAG_DATA
{
  BUTTON_DATA button;
  WINDOW_DATA window;
} DATA;

typedef struct TAG_WINDOW_T
{
  int type;
  int length;
  int height;
  int x;
  int y;
  COLOR_GROUP *color;
  BITMAP *map;
  DATA d;
} WINDOW_T;
  
void paste(WINDOW_T *w, BITMAP *m)
{
  int tmp=mouseflag;
  if (tmp)
    MouseOFF();
  blit(w->map, m, 0, 0, w->x, w->y, w->length, w->height);
  if (tmp)
    MouseON();
  return;
}
