The following code works on OS3. On OS4 apparently the WINDOW part is completely ignored and it opens a new window on the Workbench screen.

Code: Select all

/* Open a shell on a custom screen */


#include <proto/exec.h>
#include <proto/dos.h>
#include <proto/intuition.h>

#include <stdio.h>


int main (void)

{
struct Screen *scr;

if ((scr = OpenScreenTags (NULL,
		SA_LikeWorkbench,TRUE,
		TAG_END)))
	{
	struct Window *win;

	if ((win = OpenWindowTags (NULL,
			WA_CustomScreen,scr,
			WA_Flags, WFLG_ACTIVATE | WFLG_BORDERLESS | WFLG_NOCAREREFRESH,
			TAG_END)))
		{
		char conname[50];
		BPTR con;

		sprintf (conname,"CON://///WINDOW %lx",win);

		if ((con = Open (conname,MODE_READWRITE)))
			{
			Execute ("",con,(BPTR)0);
			Close (con);
			}

		if (scr->FirstWindow == win)
			CloseWindow (win);
		}

	CloseScreen (scr);
	}

return (RETURN_OK);
}

Is there an OS4.1FE manner to do this with SystemTags, because Execute() DOS call is deprecated…

Thank you

Example of running a custom shell in a screen, window for OS4.1(FE) welcomes ?

Can find a custom shell source program in the RKMs litterature ?

Thomasrapp example page 1 of this thread, uses Execute("", bptr, bptr) but it is deprecated.

Sincerely

DGILLES

As Polluks indicated above.
The SystemTags() call is what you are after, to do what the old Execute() function is doing.
See the SYS_ExecuteInputStream and SYS_Input tags.

Thank a lot

This is new to me v53.45

It answers my questions and I think furthermore that I must provide a console descriptor for the input file handle (SYS_Input).
