Classes

• template <class Ch, class Tr = std::char_traits<Ch>>
class sys::basic_packetbuf

  Stream buffer that can reads/writes data in packets with arbitrary header.

  • By default header size is nought, and packet buffer works as a regular stream buffer.

• template <class Ch, class Tr = std::char_traits<Ch>>
class sys::basic_websocketbuf

  Stream buffer that encodes/decodes its contents using WebSocket protocol. The implementation

  • supports only the latest WebSocket standard,
  • supports only binary frames,
  • supports only binary WebSocket protocol,
  • does not perform closing handshake,
  • always masks payloads,
  • uses secure random device for key generation and masking.

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

  Stream buffer that writes and reads from file descriptor.

  Fd

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

  • Input/output file descriptor operations are assumed to be non-blocking.
  • Does not flush its contents when closed.

• template <class Ch, class Tr = std::char_traits<Ch>>
class sys::basic_shmembuf

  Shared memory stream buffer with synchronisation via process_semaphore.

  Ch

  character type

  
  

  Tr

  character traits type

  
  

  • The class provides both std::streambuf and std::mutex interfaces.
  • Methods lock and unlock must be called in both parent and child process to syncrhonise buffer state updates.
