Creates a specified registry key by providing access to the Windows registry routine RegCreateKeyEx. If the key already exists, this function opens it (same functionality as REG_OPEN_KEY_EX). If the key does not exist, it is created and then opened. This library routine works with 32-bit Windows only.
Usage
Call "REG_CREATE_KEY_EX"
USING OPEN-KEY-HANDLE,
SUBKEY-TO-BE-CREATED,
CLASS-NAME,
OPTIONS,
SAM-DESIRED,
SUBKEY-HANDLE,
DISPOSITION
GIVING STATUS-CODE
Parameters
OPEN-KEY-HANDLE Usage unsigned-long
Handle of a currently open key or one of the following predefined handles of keys that are always open (defined in acugui.def):
HKEY_CLASSES_ROOT HKEY_CURRENT_USER HKEY_LOCAL_MACHINE HKEY_USERS
The key created or opened by REG_CREATE_KEY_EX is a subkey of the key identified by OPEN-KEY-HANDLE.
SUBKEY-TO-BE-CREATED PIC X(n)
Name of the subkey to create or open.
CLASS-NAME PICX (n)
Specifies the class (object type) of the key to be created. This parameter is ignored if the key already exists.
OPTIONS Usage unsigned-long
Specifies special options for the key. This parameter must be one of the following values values (defined in acugui.def):
REG_OPTION_VOLATILE --The value of this key varies depending on the Windows operating system used:
Windows 95: This value is ignored in Windows 95. That is, even if REG_OPTION_VOLATILE is specified, the RegCreateKeyEx function creates a nonvolatile key and returns ERROR_SUCCESS.
Windows NT: This key is volatile; the information is stored in memory and is not preserved when the system is restarted.
REG_OPTION_NON_VOLATILE --This key is not volatile; the information is stored in a file and is preserved when the system is restarted.
By default, keys are not volatile. This option is ignored if the key already exists.
SAM-DESIRED Usage unsigned-long
Specifies a security access mask (SAM) that describes the desired security access for the new key. This parameter can be a combination of the following values (defined in acugui.def):
KEY_ALL_ACCESS --Combination of KEY_QUERY_VALUE, KEY_ENUMERATE_SUB_KEYS, KEY_NOTIFY, EY_CREATE_SUB_KEY, KEY_CREATE_LINK, and KEY_SET_VALUE access.
KEY_CREATE_LINK --Permission to create a symbolic link.
KEY_CREATE_SUB_KEY --Permission to create subkeys.
KEY_ENUMERATE_SUB_KEYS --Permission to enumerate subkeys.
KEY_EXECUTE --Permission for read access.
KEY_NOTIFY --Permission for change notification.
KEY_QUERY_VALUE --Permission to query subkey data.
KEY_READ --Combination of KEY_QUERY_VALUE, KEY_ENUMERATE_SUB_KEYS, and KEY_NOTIFY access.
KEY_SET_VALUE --Permission to set subkey data.
KEY_WRITE --Combination of KEY_SET_VALUE and KEY_CREATE_SUB_KEY access.
The above values may be combined in COBOL applications by using the "CBL_OR" library routine.
SUBKEY-HANDLE Usage unsigned-long
Data item to receive the handle of the newly created or opened key.
DISPOSITION Usage unsigned-long
REG_CREATED_NEW_KEY --The key did not exist and was created.
REG_OPENED_EXISTING_KEY --The key existed and was simply opened without being changed.
Points to a variable that receives one of the following disposition values (defined in acugui.def):
STATUS-CODE Numeric data item
Receives the return status of the call to Microsoft's "RegCreateKeyEx" function. A return status of zero indicates success; non-zero indicates that an error occurred.
