Article
02/22/2024

The IPrintCoreHelper::EnumFeatures method gets a list of all available features, including synthesized and core driver-implement features.

Syntax

HRESULT EnumFeatures(
  [out] PCSTR * [] pFeatureList,
  [out] DWORD      *pdwNumFeatures
);

Parameters

[out] pFeatureList

A pointer to an array of ANSI character strings that contain all of the features that are available for the current device. The final array element is indicated by a NULL string. The array elements should be considered constants. The caller does not need to provide a buffer for the array, nor should the caller release the array.

[out] pdwNumFeatures

A pointer to a variable that receives the number of feature keywords in the array that is pointed to by the pFeatureList parameter.

Return value

IPrintCoreHelper::EnumFeatures should return S_OK if the operation succeeds. Otherwise, this method should return a standard COM error code.

Remarks

For Unidrv features, the feature list is based on the GPD view of the configuration file, so features that are surrounded by Ifdef GDL_ENABLED / Endif directives are not visible and will not be reported by IPrintCoreHelper::EnumFeatures.
