I have a third-party dll that I load into software that isn\'t mine, and I\'m using AllocConsole() to create the standard windows CLI window so I have an easy means of outpu
Thanks to Ben Voigt, I was able to cause the console to take input after I allocated it by doing:
freopen("CONIN$", "r", stdin);
freopen("CONOUT$", "w", stdout);
freopen("CONOUT$", "w", stderr);
This also directs the stdout and strerr to the same console window, in case they are directed someplace else for some reason.
This is what I use.
FILE *file = nullptr;
freopen_s(&file,"CONIN$", "r", stdin);
freopen_s(&file, "CONOUT$", "w", stdout);
Just hopes this helps someone.
This is the code that works for me:
freopen("CONOUT$", "w", stdout);
You can probably do something similar with CONIN$
and stdin
(Open for read, of course).
Do you also redirect the stdout
and stderr
to your console?
I used this code to get access to the JavaVM output from a Windows app.
if(::AllocConsole())
{
int hCrt = ::_open_osfhandle((intptr_t) ::GetStdHandle(STD_OUTPUT_HANDLE), _O_TEXT);
FILE *hf = ::_fdopen( hCrt, "w" );
*stdout = *hf;
::setvbuf(stdout, NULL, _IONBF, 0 );
hCrt = ::_open_osfhandle((intptr_t) ::GetStdHandle(STD_ERROR_HANDLE), _O_TEXT);
hf = ::_fdopen( hCrt, "w" );
*stderr = *hf;
::setvbuf(stderr, NULL, _IONBF, 0 );
}
After this I can see all stdout
and stderr
outputs from the VM.
