IVdsAsync interface (vdshwprv.h)
Manages asynchronous operations. Methods that initiate asynchronous operations return a pointer to an IVdsAsync interface, allowing the caller to optionally cancel, wait for, or query the status of the asynchronous operation.
The IVdsAsync interface inherits from the IUnknown interface. IVdsAsync also has these types of members:
The IVdsAsync interface has these methods.
The IVdsAsync::Cancel method (vdshwprv.h) cancels the asynchronous operation.
The IVdsAsync::QueryStatus method (vdshwprv.h) returns when the asynchronous operation is in progress, has finished successfully, or has failed.
The IVdsAsync::Wait method (vdshwprv.h) returns when the asynchronous operation has either finished successfully or failed.
