Assuming Windows: AllocConsole().

Call it once at startup and use WriteConsole() to write to it. The handle you need can be obtained by calling GetStdHandle() with an argument of STD_OUTPUT_HANDLE.

Sample code:


AllocConsole();
HANDLE consoleHandle = GetStdHandle(STD_OUTPUT_HANDLE);

...

// This is using a non-wide string. You may want to use WriteConsoleW if you need extended characters.
WriteConsoleA(consoleHandle, "Hello World", strlen("Hello World"), NULL, NULL);

Sample code:

*** Source Snippet Removed ***



AllocConsole();

freopen("CONOUT$", "w", stdout);
freopen("CONOUT$", "w", stderr);
freopen("CONIN$", "r", stdin);





with this he'll be able to use printf or cout
