I have a VC++ program that uses a Cygwin-compiled DLL. I can init cygwin1.dll
but, after doing this, cout and cerr stop working. cout << "Message" << endl
does not appear on the screen. I do not know exactly what happens here. The
program is:
/me repeats Dave's comment
cout << "Before" << endl; // Appears
HMODULE cygwinDll = LoadLibrary("cygwin1.dll");
void (*init)() = (void (__cdecl *)(void)) GetProcAddress(cygwinDll,
"cygwin_dll_init");
init();
cout << "After" << endl; // Does nor appear
What is going on here?? What do I have to do to have cout and cerr back
normally??
Does it work if you /don't/ use cout before cygwin_dll_init()?
My guess would be "don't expect to be able to use cout/cerr before /and/
after calling cygwin_dll_init()". This just "feels" like something that
would not work, nor should you probably be doing it. I would think that
calling cygwin_dll_init() needs to be /the very first thing you do/. In
fact, doing anything with stdin/stdout/stderr (i.e. stdio too) before
and after is probably a bad idea unless you know what you are doing.
