• template <class Ch, class Tr = std::char_traits<Ch>, class Fd = sys::fildes>
class sys::basic_ifdstream

  Input stream that reads from file descriptor.

  Fd

  File descriptor type. Can be a wrapper class or int.

  
  

  • Any type for which streambuf_traits are defined, may be used instead of file descriptor.
  • Input operations are non-blocking by default.

class sys::basic_ofdstream

  Output stream that writes to file descriptor.

  • Any type for which streambuf_traits are defined, may be used instead of file descriptor.
  • Output operations are non-blocking by default.
  • The stream does not flush buffer contents when closed.

• template <class Ch, class Tr = std::char_traits<Ch>, class Fd = sys::fildes>
class sys::basic_fdstream

  Input/output stream that reads/writes to/from file descriptor.

  • Any type for which streambuf_traits are defined, may be used instead of file descriptor.
  • Input and output operations are non-blocking by default.
  • The stream does not flush buffer contents when closed.

• class sys::osysstream

  Output stream for standard file descriptors that uses basic_fildesbuf as stream buffer.

  • The stream is designed to be used with standard file descriptors 0, 1, 2.
  • Underlying file descriptor is not closed or flushed in stream destructor.

• class sys::argstream

  Output stream of command line arguments.

  • Use append method to append one argument at a time.
