I am trying to get an application that was compiled/linked under Visual
C++ to work in a bash window.
The application requires that i/o be performed in "raw" mode, (i.e.,
using ioctl, isatty, etc calls).
When the application is run in an NT cmd window (dos prompt!), it runs
fine.
When run in a bash shell, isatty returns 0 (not in a terminal), and the
ioctl calls return
"Invalid Arguments".
Does anyone know how to make this work?
I have a Console Application created with Visual C++, and want to run it
in
a bash window.
When the application is run (see code below), printf works fine, but
isatty(fileno(stdin)) returns 0 (no terminal attached). Also any ioctl
calls return a failure
Is there any way to do this??
//
// Example code...
//
#include "stdafx.h"
#include <stdio.h>
#include <io.h>
int main(int argc, char* argv[])
{
int i;
i = _isatty(_fileno(stdin));
printf("isatty returned: %d\n", i);
return 0;
}
I also tried creating the same application using the MKS NutCracker
suite
(that application had ioctl) calls.
This application also fails (and the ioctl calls failed with "Invalid
Argument").
(A gut feeling - would compiling bash using VC++ solve the problem -
gulp!!).
