INSSBuffer Interface
The INSSBuffer interface provides methods for supporting a memory buffer. You can use this interface when you are creating custom plug-ins. For example, memory buffers are typically used by logging, data source, playlist parser, and cache proxy plug-ins.
You can allocate a buffer by using the IWMSBufferAllocatorIWMSBufferAllocator Interface. The IWMSBufferAllocator interface contains methods that create page-aligned and non-aligned buffers, depending on your requirements.
Note
This interface is available only on Windows Server 2003, Enterprise Edition; Windows Server 2003, Datacenter Edition; and Windows Server 2008.
In addition to the methods inherited from IUnknown, the INSSBuffer interface exposes the following methods.
