/* WriteRegistryData
|

|
|
*
|
|||
|
|
* Writes a bunch of information to the registry
|
|||
|
|
*
|
|||
|
|
* Parameters:
|
|||
|
|
*
|
|||
|
|
* pEntryNode - The node under szRegPath which should be created
|
|||
|
|
* or opened for this data. If this is NULL, the value is
|
|||
|
|
* written directly under szRegPath.
|
|||
|
|
*
|
|||
|
|
* pEntryName - The name of the value under pEntryNode to be set.
|
|||
|
|
*
|
|||
|
|
* Type - Type of data to read (e.g. REG_SZ).
|
|||
|
|
*
|
|||
|
|
* pData - Pointer to the value data to be written. If this is NULL,
|
|||
|
|
* the value under pEntryNode is deleted.
|
|||
|
|
*
|
|||
|
|
* Size - Size, in bytes, of the buffer pointed to by pData.
|
|||
|
|
*
|
|||
|
|
*
|
|||
|
|
* This routine is fairly generic, apart from the name of the top-level node.
|
|||
|
|
*
|
|||
|
|
* The data are stored in the following registry tree:
|
|||
|
|
*
|
|||
|
|
* HKEY_CURRENT_USER
|

|
|
* <EFBFBD>
