Simply because it doesn't work, it generates BadDrawable X error.
Check out the code below:
<code>
/* test.c
 * gcc test.c -o test -g -Wall `pkg-config --cflags --libs gdk-2.0`
*/

#include <gdk/gdk.h>
#include <X11/Xlib.h>
#include <stdio.h>

int main(int argc, char** argv)
{
   gdk_init(&argc, &argv);

   Display* display = XOpenDisplay(NULL);
   if (!display)
       return -1;

   Drawable xid = XCreatePixmap(display, DefaultRootWindow(display),
                                20, 20, 24);

   GdkPixmap* pixmap =
gdk_pixmap_foreign_new_for_display(gdk_display_get_default(), xid);

   printf("Foreign pixmap = %p\n", pixmap);

   return 0;
}
</code>

gdk_pixmap_foreign_new_for_display generates BadDrawable.
This example shows what I eventually need.
