HRESULT GetCategories(
  [out] APPCATEGORYINFOLIST *pAppCategoryList
);

Parameters

[out] pAppCategoryList

Type: APPCATEGORYINFOLIST*

A pointer to an APPCATEGORYINFOLIST structure. This structure's cCategory member returns the count of supported categories.

Remarks

The Add/Remove Programs Control Panel Application passes the ID returned for a category to the IAppPublisher::EnumApps method to identify which category is to be enumerated.

Examples
