IPrintOemUni2::GetImplementedMethod method (prcomoem.h)
The IPrintOemUni2::GetImplementedMethod method is used by Unidrv to determine which IPrintOemUni2 interface methods a rendering plug-in has implemented.
Syntax
HRESULT GetImplementedMethod(
PSTR pMethodName
);
Parameters
pMethodName
Caller-supplied pointer to a string that represents the name of an IPrintOemUni2 interface method, such as "ImageProcessing" for IPrintOemUni2::ImageProcessing or "FilterGraphics" for IPrintOemUni2::FilterGraphics.
Return value
GetImplementedMethod must return one of the following values.
| Return code | Description |
|---|---|
|
The operation succeeded (that is, the specified method is implemented). |
|
The operation failed (that is, the specified method is not implemented). |
Remarks
A rendering plug-in for Unidrv must implement the IPrintOemUni2::GetImplementedMethod method, together with several other methods in this interface. For those methods that are optional, IPrintOemUni2::GetImplementedMethod examines the input method name string and returns a value that indicates whether the associated method is implemented within the plug-in. For example, if IPrintOemUni2::GetImplementedMethod is called with the string "ImageProcessing", it should return S_OK if the IPrintOemUni2::ImageProcessing method is implemented and S_FALSE otherwise.
The IPrintOemUni2::GetImplementedMethod method must recognize the following name strings:
"CommandCallback"
"Compression"
"DownloadCharGlyph"
"DownloadFontHeader"
"FilterGraphics"
"HalftonePattern"
"ImageProcessing"
"MemoryUsage"
"OutputCharStr"
"SendFontCmd"
"TextOutAsBitmap"
"TTDownloadMethod"
"TTYGetInfo"
"WritePrinter"
