CAtlTransactionManager::RegCreateKeyEx

  • Artículo

Creates the specified registry key and associates it with a transaction. If the key already exists, the function opens it.

inline LSTATUS CAtlTransactionManager::RegCreateKeyEx(
   HKEY hKey,
   LPCTSTR lpSubKey,
   DWORD dwReserved,
   LPTSTR lpClass,
   DWORD dwOptions,
   REGSAM samDesired,
   CONST LPSECURITY_ATTRIBUTES lpSecurityAttributes,
   PHKEY phkResult,
   LPDWORD lpdwDisposition
);

Parameters

  • hKey
    A handle to an open registry key.

  • lpSubKey
    The name of a subkey that this function opens or creates.

  • dwReserved
    This parameter is reserved and must be zero.

  • lpClass
    The user-defined class of this key. This parameter may be ignored. This parameter can be NULL.

  • dwOptions
    This parameter can be one of the following values: REG_OPTION_BACKUP_RESTORE, REG_OPTION_NON_VOLATILE, or REG_OPTION_VOLATILE.

  • samDesired
    A mask that specifies the access rights for the key.

  • lpSecurityAttributes
    Pointer to a SECURITY_ATTRIBUTES structure that determines whether the returned handle can be inherited by child processes. If lpSecurityAttributes is NULL, the handle cannot be inherited.

  • phkResult
    A pointer to a variable that receives a handle to the opened or created key. If the key is not one of the predefined registry keys, call the RegCloseKey function after you have finished using the handle.

  • lpdwDisposition
    A pointer to a variable that receives one of the following disposition values: REG_CREATED_NEW_KEY or REG_OPENED_EXISTING_KEY.

Return Value

If the function succeeds, the return value is ERROR_SUCCESS. If the function fails, the return value is a nonzero error code defined in Winerror.h.
