DrvSaveParametersKey

BOOL
    DrvSaveParametersKey(
        PREG_ACCESS RegAccess
        );

The DrvSaveParametersKey function saves the current contents of the driver’s \Parameters registry key, along with its subkeys, in a temporary file.

Parameters

RegAccess

Pointer to a globally-defined structure of type REG_ACCESS.

Return Value

Returns TRUE if the operation succeeds. Otherwise returns FALSE.

Comments

The structure pointed to by RegAccess must be a single, globally-defined REG_ACCESS structure that the driver uses with all calls to drvlib.lib functions requiring a RegAccess parameter.

If the DrvSaveParametersKey function succeeds, the REG_ACCESS structure contains the name of the temporary file.

To restore the saved registry information, call DrvRestoreParametersKey.

Drivers must call DrvCreateServicesNode before calling DrvSaveParametersKey.
