Syntax

'Declaration
Sub CancelOperation ( _
    pCancelledOperationContext As UccOperationContext, _
    pOperationContext As UccOperationContext _
)

void CancelOperation (
    UccOperationContext pCancelledOperationContext,
    UccOperationContext pOperationContext
)

void CancelOperation (
    UccOperationContext^ pCancelledOperationContext, 
    UccOperationContext^ pOperationContext
)

void CancelOperation (
    UccOperationContext pCancelledOperationContext, 
    UccOperationContext pOperationContext
)

function CancelOperation (
    pCancelledOperationContext : UccOperationContext, 
    pOperationContext : UccOperationContext
)

Parameters

  • pCancelledOperationContext
    A value of the IUccOperationContext* (UccOperationContext, for a .NET application) type. The default value is NULL. This specifies the operational context for this method.
  • pOperationContext
    A value of the IUccOperationContext* (UccOperationContext, for a .NET application) type. The default value is NULL. This refers to the operational context of the to-be-canceled pending request.

Remarks

This method is an asynchronous operation. It is currently applicable to canceling a pending IUccAudioVideoSessionParticipant::UpdateChannels operation.

Win32 COM/C++ Syntax

HRESULT CancelOperation
(
   IUccOperationContext* pCancelledOperationContext,
   IUccOperationContext* pOperationContext
);

Note

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.

Thread Safety

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