WinAPI functions - similar functions as part of VS C++

If someone could explain all the "flavors" of functions.

For example, there is a winAPI: GetLogicalDrives

But, it seems there is a _getdrives function which mimic GetLogicalDrives. What is the term for "what" _getdrives is vs. GLD which is a win API function?

Which should one use? Do these decisions/choices make any difference?

It's a CRT function, as in, you can't use it unless you're using Microsoft's C Run-Time

Whichever one you want, they both tie the code to Windows

Not following. Is _getdrives statically bound/linked into my C program's .exe? Or, is _getdrives search/found at run-time only?
