To support running code you'll need to call mprotect(2) on the buffer to make it executable.

If you hit Ctrl-d on this code it will burn through that loop constantly with no input. You need to check fgets()'s return code, it will be NULL on error or eof.

Thank you. I saw a warning about that from the compiler. But like I said I'm not a C programmer. Feel free to submit a PR if you like.

I assume you're talking about Linux/Unix. I'm mostly a Windows guy.

I am knowledgeable about both. Unix guy at heart but used to work for MSFT on windows.

The Windows version of mprotect(2) is VirtualProtect. It would probably make more sense to allocate the buffer with VirtualAlloc with the correct flags, rather than modify a stack buffer. The Unix version of that would be to allocate with mmap(2).
