RegcreateKey
(For more information, http://websl.126.com)
The regcreateKey function creates a new reference button. If this button already exists in the registry, this function opens it. This function is compatible with Windows 3.1. Win32-based applications should use the RegcreateKeyex function.
Long regcreateKey
HKEY HKEY, / / Handle to open the key
LPCTSTR LPSUBKEY, / / Address to open the name of the subkey
Phkey phkResult // The address of the buffer of the handle is opened
);
parameter
HKEY
The handle of the current open button or the following has been determined to keep the handle value:
HKEY_CLASS_ROTHKEY_CURRENT_CONFIGHKEY_CURRENT_USERHKEY_LOCAL_MACHINEHKEY_USERSWINDOWS NT: HKEY_PERFORMANCE_DATA Windows 95 and Windows 98: HKEY_DYN_DATA
The sub-key of the key recognized by HKEY is open or newly created by RegcreateKey.
LPSUBKEY
Point to a string that contains empty characters over or the name to open or new. This key must be a subkey that can be identified by the HKEY parameter.
If HKEY is one of the confirmed kept values, LPSUBKEY can be NULL. In this case, the function phkResult returns the same handle as being passed.
PhkResult
Point variables that receive open or new built keys. When you no longer need to return your handle, call
RegcloseKey function close it
return value
Returns Error_Success if the call is successful.
If the call fails, a non-zero error code is returned (defined in WineError.h). You can use the FormatMessage function with the format_message_from_system tag to get normal error description information.
note
An application can use the RegcreateKey function to create a new separate key at a time. For example, an application can create a four-level sub-key (including the three levels of the previous three levels of a given button) like a LPSUBKEY parameter string below:
Subkey1 / Subkey2 / Subkey3 / Subkey4
This key that can be identified by the HKEY parameter must be opened with key_create_sub_key access (key_write access permissions including key_create_ssub_key access).
If the lpsubkey parameter is an empty string address, the function opens and transmits the key that can be identified by the HKEY parameter.
