[Coco] OS9 Save and Restore Window

[tim lindner]

On RTSI there is a library call Window_SaveRestore_fncs.lzh. It allows
recording all of the characteristics of a Windint window. This is nice
to be able to save a window, change it and then change it back. But I
found a problem that I don't fully understand.

Here is the program:

/* status.c - testing cgfx status functions */

#include <stdio.h>
#include <sgstat.h>
#include <window.h>
#include <buffs.h>
#define STDIN 0
#define STDOUT 1
#define BLACK 2

main()
{
    WINDOW *w;
    w = getwind(STDOUT);
    DWEnd(STDOUT);
    DWSet(STDOUT,8,0,0,40,24,0,1,2);
    system( "merge /dd/sys/stdfonts" );
    Font(STDOUT,GRP_FONT,FNT_S8X8);
    Select(STDOUT);
    CurOff(STDOUT);
    BColor(STDOUT,0);
    FColor(STDOUT,1);
    Clear(STDOUT);
    CurXY(STDOUT,6,10);
    write(STDOUT,"This is now a Type 8 window!",28);
    tsleep(300);
    Clear(STDOUT);
    CurXY(STDOUT,8,9);
    write(STDOUT,"I will now reset back to",24);
    CurXY(STDOUT,8,11);
    write(STDOUT,"original characteristics",24);
    tsleep(180);
    if(w != NULL)
        setwind(STDOUT,w);
    Select(STDOUT);
}

The library and the above program work well when run from the command
line. But when you run the program with the standard input redirected
from a file, it doesn't. The screen goes blank, and the returns to
normal after the program finishes.

This means I can't run the program from a shell script. I've tried the
program with the newest NitrOS-9 and also stock OS-9. Both exhibit the
same behaivor.

I would like to find the root cause of what I am seeing. But I need to
ask, Is there something in OS-9 that would keep this from working? Or
have I found a bug?
