Catching ERROR_ALREADY_EXISTS and similar errors with CreateDirectory()

Question

I am looking to make a program using CreateDirectory(), RemoveDirectory(), and similar functions. One of the possible return errors from these commands ERROR_ALREADY_EXISTS. I want an if statement to catch this error and post a message on the screen and continue.

Answer 1

You need to call GetLastError () and check to see if the error condition meets ERROR_ALREADY_EXISTS; after calling CreateDirectory() and when it returns 0.
