Abstract:
|
|
|
|
Routines that manage the merging of registry keys. Given a key
|
|
and a value, these functions allow the user to perform the same
|
|
types of actions as those specified in usermig.inf and wkstamig.inf
|
|
(i.e.: Copying, Suppressing, and Forcing various registry keys to be
|
|
merged into the NT registry.)

Routine Description:
|
|
|
|
IsRegObjectMarkedForOperation builds an encoded key, escaping multi-byte
|
|
characters and syntax characters, and then performs a MemDb lookup to see
|
|
if the object is marked with the bit specified by OperationMask. A set of
|
|
macros are built on top of this routine in regops.h.
|
|
|
|
Arguments:
|
|
|
|
Key - Specifies the unencoded registry key, with abriviated roots
|
|
(i.e., HKLM\Software\Foo)
|
|
Value - Specifies the registry key value name
|
|
TreeState - Specifies KEY_ONLY to query against the key and optional
|
|
value, KEY_TREE to query against the key with a star at the
|
|
end, or TREE_OPTIONAL to query both.
|
|
OperationMask - Specifies an operation mask. See merge.h.
|
|
|
|
Return Value:
|
|
|
|
TRUE if the key is in MemDb, or FALSE if it is not.

Routine Description:

MarkRegObjectForOperation creates an encoded string and sets the operation

Key - Specifies an unencoded registry key, with abriviated root

Value - Specifies the registry key value name.

Tree - Specifies TRUE if Key specifies an entire registry key tree

|
|
specifies a key that has different behavior for its subkeys.
|
|
OperationMask - Specifies the suppression operation. See merge.h.
