Hi there,
I'm writing a windows "winmain()" application which talks to the
console, and am having trouble getting it to write() to a cygwin console
window. I was hoping that someone on this list might be able to aid me.
The application is a dual graphics/CLI program, and so needs to detect
whether it is running in a terminal first. If it is then it runs in
console mode, otherwise it opens a graphics window (using directx). As
such it has a winmain() instead of a main(), and therefore the
stdin/stdout channels aren't immediately available to it.
Here's what it does:
// If we can attach to the parent terminal then we were run in a
console window.
if (AttachConsole(ATTACH_PARENT_PROCESS))
{
m_CLIApp = true;
}
...
If (m_CLIApp) {
// XXX Test output to the console. Why doesn't this
approach work in a cygwin console window?
// XXX Where does the output go in that case?
char s[] = "This is the console\r\n";
unsigned long cChars;
WriteConsole(GetStdHandle(STD_OUTPUT_HANDLE), s,
lstrlen(s), &cChars, NULL);
}
Does anyone know why this doesn't output to a cygwin console, although
it does if started in a cmd shell?
Joe
