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 IWMSBufferAllocator 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.

Method Description
GetBuffer Retrieves an allocated buffer.
GetBufferAndLength Retrieves a buffer object and the length of data segment that can be loaded into it.
GetLength Retrieves the length of data segment that can be loaded into the buffer.
GetMaxLength Retrieves the maximum length of data segment that can be loaded into the buffer.
SetLength Specifies the length of data segment that can be loaded into the buffer.
