What is the difference in calling the Win32 API function that have an A character appended to the end as opposed to the W character.
I know it means ASCII and WIDE CHARACTER or Unicode, but what is the difference in the output or the input?
For example, If I call GetDefaultCommConfigA, will it fill my COMMCONFIG structure with ASCII strings instead of WCHAR strings? (Or vice-versa for GetDefaultCommConfigW)
In other words, how do I know what Encoding the string is in, ASCII or UNICODE, it must be by the version of the function I call A or W? Correct?
I have found this question, but I don't think it answers my question.
