The SetupDiClassNameFromGuidEx function retrieves the class name associated with a class GUID. The class can be installed on a local or remote computer.
The class GUID of the class name to retrieve.
A pointer to a string buffer that receives the NULL-terminated name of the class for the specified GUID.
The size, in characters, of the ClassName buffer.
The number of characters required to store the class name (including a terminating null). RequiredSize is always less than MAX_CLASS_NAME_LEN.
A pointer to a NULL-terminated string that contains the name of a remote system on which the class is installed. This parameter is optional and can be NULL. If MachineName is NULL, the local system name is used.
Caution
Using this function to access remote machines is not supported beginning with Windows 8 and Windows Server 2012, as this functionality has been removed.
Must be NULL.
The function returns TRUE if it is successful. Otherwise, it returns FALSE and the logged error can be retrieved with a call to GetLastError.
Note
The setupapi.h header defines SetupDiClassNameFromGuidEx as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
