Prefix of each buffer, in bytes. If the value is non-zero, each buffer pointer returned by the CBaseAllocator::GetBuffer method is preceded by a block of bytes of size m_lPrefix. This memory block is called the prefix. The CBaseAllocator::m_lSize member variable does not include the prefix value.

Syntax

  long m_lPrefix;

Requirements

**  Header:** Declared in Amfilter.h; include Streams.h.
