    How can my plugin command test whether it is on the right side of a pipe?

    Thanks.

    I do something like this:

    Code:
    wchar_t shortbuf[shortbuflen] = L"%[_transient]%[_pipe]";
ExpandVariables( shortbuf, 1 );

if ( wcscmp( shortbuf, L"00" ) == 0 ) {
    //  do stuff ....
}

    I knew that (but didn't think of it, thanks). I was asking how to do it with the API (Win32 or TCC/SDK). I test for the left side of a pipe or redirection by seeing if GetConsoleScreenBufferInfo() works.

    P.S. I use as little of the wcs stuff as possible; it keeps the DLL smaller. KERNEL32 exports several useful lstr... functions.

    Does isatty(fileno(stdin)) do what you want? It appears to return properly
    in my tests.
