SHEnumKeyExA function (shlwapi.h)
Enumerates the subkeys of the specified open registry key.
LSTATUS SHEnumKeyExA( [in] HKEY hkey, DWORD dwIndex, LPSTR pszName, [in] LPDWORD pcchName );
A handle to the currently open key, or any of the following predefined values.
The index of the subkey to retrieve. This parameter should be zero for the first call and incremented for subsequent calls.
The address of a character buffer that receives the enumerated key name.
The address of a DWORD that, on entry, contains the size of the buffer at pszName, in characters. On exit, this contains the number of characters that were copied to pszName.
Returns ERROR_SUCCESS if successful, or a nonzero error code defined in Winerror.h otherwise. You can use the FormatMessage function with the FORMAT_MESSAGE_FROM_SYSTEM flag to retrieve a textual description of the error.
The shlwapi.h header defines SHEnumKeyEx 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.
