REMARKS: The address specified by the lpszSvPack parameter will be filled with a null-terminated string (such as "Service Pack 2") specifying the last service pack installed. This string can be empty if no service pack has been installed on the system. If the lpszSvPack parameter is a NULL pointer, then it is ignored and no information about the service pack is returned.

REMARKS:The lpszSvPack parameter will be filled with a Unicode string if the application is running as Unicode. Otherwise, it will be filled with an ANSI string (see the IsAppUnicode method). You can call GetPlatformA to get an ANSI string in Unicode applications, or GetPlatformW to get a Unicode string in ANSI applications.
