LDR_RegEnumKey

DWORD LDR_RegEnumKey(HKEY hKey, DWORD iSubKey, LPSTR lpszBuffer, 
      DWORD cbBuffer)

• Returns ERROR_SUCCESS if successful; otherwise, one of the error values given in Error Values.

hKey

Handle of a previously opened key or is the HKEY_LOCAL_MACHINE key.

iSubKey

Index of the subkey to retrieve. This should be zero for the first call to this API.
