Detailed Description

Interface providing read access to a memory read file.

Member Function Documentation

getBuffer()

virtual const void * dcpp::io::IMemoryReadFile::getBuffer ( ) const

pure virtual

Get direct access to internal buffer of memory block used as file.

It's usually better to use the IReadFile functions to access the file content. But as that buffer exist over the full life-time of a PMemoryReadFile, it's sometimes nice to avoid the additional data-copy which read() needs.
