Win32 COM/C++ Syntax

HRESULT GetCategoryInstances
   BSTR bstrCategoryName,
   IUccCollection** ppCategoryInstanceCollection
In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Trace and Handle Errors in Unified Communications Client API.

The following public method is exposed by a client application class that wraps an IUccContainer instance. The property returns the collection of category instances (IUccCategoryInstance).

public IUccCollection CategoryInstanceCollection(string pCategoryName)
   return this._container.GetCategoryInstances(pCategoryName);

All public static (Shared in Visual Basic) members of this type are thread-safe. Instance members are not guaranteed to be thread-safe.
