streambuf
Layer
The istream
and ostream
classes are meant to handle
conversion between objects in your program and their textual representation.
By contrast, the underlying streambuf
class is for transferring
raw bytes between your program, and input sources or output sinks.
Different streambuf
subclasses connect to different kinds of
sources and sinks.
The GNU implementation of streambuf
is still evolving; we
describe only some of the highlights.
Areas Areas in a streambuf. Overflow Simple output re-direction Formatting C-style formatting for streambuf objects. Stdiobuf Wrappers for C stdio. Procbuf Reading/writing from/to a pipe Backing Up Marking and returning to a position. Indirectbuf Forwarding I/O activity.
