The IPrintOemUni::ResetPDEV method allows a rendering plug-in for Unidrv to reset its PDEV structure.
Syntax
HRESULT ResetPDEV(
PDEVOBJ pdevobjOld,
PDEVOBJ pdevobjNew
);
Parameters
pdevobjOld
Caller-supplied pointer to a DEVOBJ structure containing current PDEV information.
pdevobjNew
Caller-supplied pointer to a DEVOBJ structure into which the method should place new PDEV information.
Return value
The method must return one of the following values.
| Return code | Description |
|---|---|
|
The operation succeeded. |
|
The operation failed. |
If the operation fails, this method should call SetLastError.
Remarks
A rendering plug-in for Unidrv must implement the IPrintOemUni::ResetPDEV method.
A rendering plug-in's IPrintOemUni::ResetPDEV method performs the same types of operations as the DrvResetPDEV function that is exported by a printer graphics DLL. During the processing of an application's call to the Microsoft Windows SDK ResetDC function, the IPrintOemUni::ResetPDEV method is called by the DrvResetPDEV function in Unidrv's printer graphics DLL. For more information about when DrvResetPDEV is called, see its description.
The rendering plug-in's private PDEV structure's address is contained in the pdevOEM member of the DEVOBJ structure pointed to by pdevobjOld. The IPrintOemUni::ResetPDEV method should use relevant members of this old structure to fill in the new structure, which is referenced through pdevobjNew.
