Detailed Description

An input stream buffer.

An input stream buffer which reads from a file descriptor. This provides input buffering.

Constructor & Destructor Documentation

constructor

Constructor which accepts the file descriptor to read from.

Parameters

fd	the file descriptor to read from
isCloseNeeded	a flag indicating whether the file descriptor is closed on destruction
owner	our owning input stream

char VICI::cfi::fdinbuf::mBuffer[BUFFER_SIZE+PUSHBACK_SIZE]

protected
