When learning Windows API multithreading using C, many tutorials often mention the concept of the "main thread." However, I haven't found this concept clearly defined in the official documentation. Is the main thread simply the one running the main function？
When you launch a Windows application, the operating system creates a process and, as part of that, creates a single thread that starts executing at the entry point of your program. This initial thread is what is referred to as the main thread. Any additional threads you create (using functions like CreateThread) are considered secondary threads.
So, yes, in a nutshell, the main thread is simply the one running the main (or WinMain) function.
