Routine Description:
|
|
|
|
Set the type and value of an open key. Changes are not committed
|
|
until the key is flushed. By "committed" we mean written to disk.
|
|
Changes will be seen by subsequent queries as soon as this call
|
|
returns.
|
|
|
|
Arguments:
|
|
|
|
hKey - Supplies a handle to the open key. Any of the predefined
|
|
reserved handles or a previously opened key handle may be used for
|
|
hKey.
|
|
|
|
lpValueName - Supplies the name of the value to set. If the ValueName
|
|
is not present, it is added to the key.
|
|
|
|
dwType - Supplies the type of information to be stored: REG_SZ, etc.
|
|
|
|
lpData - supplies a pointer to a buffer containing the data to set for
|
|
the value entry.
|
|
|
|
cbData - Supplies the length (in bytes) of the information to be stored.
|
|
|
|
Return Value:
|
|
|
|
Returns ERROR_SUCCESS (0) for success; error-code for failure.
|
|
|
|
Notes:
|
|
|
|
A set may fail due to memory limits - any config entry must fit in
|
|
main memory. If successful, RegSetValue will set the type, contents,
|
|
and length of the information stored at the specified key.
|
|
KEY_SET_VALUE access is required.
