The function RegOpenKeyExA is the ANSI version of the RegOpenKeyEx, which is a wrapper to the function RegOpenKeyExW, the UTF-16 version.

In the context of the functions in question, the ANSI version requires the second parameter (i.e. the name of the registry subkey to be opened) to be of a LPCSTR type whereas the UTF-16 version requires the same parameter to be of a LPCWSTR type.
