FBB::IFdStream(3bobcat)  File Descriptor Input Stream  FBB::IFdStream(3bobcat)



NAME
       FBB::Ifdstream - Input Stream initialized by a File Descriptor

SYNOPSIS
       #include <bobcat/ifdstream> (when using FBB::IFdStream
       #include <bobcat/ifdstreams> (when using FBB::IFdStreamS

       Linking option: -lbobcat

DESCRIPTION
       FBB::IFdStream objects are used to extract information from devices
       whose file descriptors are available.

       FBB::IFdStreamS objects operate like FBB::IFdStream objects but use
       FBB::Selector objects to check whether information on the object's file
       descriptor is available before reading information from the file
       descriptor.

       File descriptors are not defined within the context of C++, but they
       can be used on operating systems that support the concept. Realize that
       using file descriptors introduces operating system dependencies.

       Note that sockets can be used as file descriptors.

NAMESPACE
       FBB
       All constructors, members, operators and manipulators, mentioned in
       this man-page, are defined in the namespace FBB.

INHERITS FROM
       std::istream

CONSTRUCTORS
       o      IFdStream(int fd, size_t n = 1):
              The constructor initializes the object to read from descriptor
              fd, using a buffer of size n, by default having size 1.
              Use IFdStreamS(int fd, size_t n = 1) to construct an IFdStreamS
              object.


       Copy and move constructors (and assignment operators) are not
       available.

MEMBER FUNCTIONS
       All members of std::istream are available, as FBB::IFdStream(S)
       inherits from this class. There are no additional members.

EXAMPLE
       See the clientsocket(3bobcat) man-page for an example showing how to
       use IFdStream.

FILES
       bobcat/ifdstream - defines the FBB::IFdStream class interface
       bobcat/ifdstreams - defines the FBB::IFdStreamS class interface

SEE ALSO
       bobcat(7), ifdbuf(3bobcat), ofdstream(3bobcat), selector(3bobcat)

BUGS
       The IFdStream(S) object uses an IFdBuf(S) for its std::streambuf. This
       buffer is associated with the file descriptor passed to IFdStream(S)'s
       constructor. When the IFdStream(S) object goes out of scope the device
       (file, socket, etc.) to which the file descriptor that was passed to
       IFdStream(S)'s constructor is not closed.
