How do I access console output in a WinMain C program?

Dealing with Console Output in a Windows C Program

When working with a native C Windows program with a WinMain entry point, accessing console output from functions like std::cout can be challenging. Here are some solutions:

Redirect Console Output

The article "Adding Console I/O to a Win32 GUI App" suggests redirecting console output to a text file. Alternatively, you can redirect it to a console using the "guicon.cpp" code provided in the response. This code creates a console and redirects unbuffered standard input, output, and error handles to it, making std::cout output visible.

Alternatives to std::cout

If modifying the code or using a console is not feasible, consider using platform-specific output functions like OutputDebugString, printf, or debugging tools like Visual Studio's debugging output window.

Using CrtDbg

For C memory debugging, the "guicon.cpp" code can be modified to redirect CrtDbg output (such as _RPT0) to the console for debugging purposes.
