BufferCommand enumeration

Note

The Microsoft Foundation Classes (MFC) library continues to be supported. However, we're no longer adding features or updating the documentation.

Used by CMemFile::GetBufferPtr to determine what action to take on the file-backed memory buffer.

Syntax

public enum BufferCommand
{
   bufferRead,
   bufferWrite,
   bufferCommit,
   bufferCheck
};

Members

bufferWrite	Write to the file-backed memory buffer.
