Alias to basic_fildesbuf<char>.

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.

Base classes

• public virtual std::basic_streambuf< Ch, std::char_traits< Ch > >

Types

• using fd_type = Fd

  File descriptor type.

Methods

• available() const -> std::streamsize

  Returns the number of available bytes in get buffer.

• remaining() const -> std::streamsize

  Returns the number of remaining bytes in put buffer.

• dirty() const -> bool

  Returns true, if put buffer is non-empty.

• swap(basic_fildesbuf & rhs) -> void

  Swap with rhs.

• compact() -> void

  Compact buffer.

• close() -> void

  Close file descriptor.

• fd() -> fd_type &

  Get file descriptor.

• fd() const -> const fd_type &

  Get file descriptor.

• setfd(fd_type && rhs) -> void

  Set file descriptor.

• pubfill() -> std::streamsize

  Fill get area from file descriptor.

• pubflush() -> std::streamsize

  Flush put area contents to file descriptor.

• sync() -> int

  Overrides std::streambuf::sync.

• xsputn(const char_type * s, std::streamsize n) -> std::streamsize

  Overrides std::streambuf::xsputn.

• xsgetn(char_type * s, std::streamsize n) -> std::streamsize

  Overrides std::streambuf::xsgetn.

• underflow() -> int_type

  Overrides std::streambuf::underflow.

• basic_fildesbuf(fd_type && fd, size_type gbufsize, size_type pbufsize)

  Construct the buffer with file descriptor fd, get area size gbufsize and put area size pbufsize.

• basic_fildesbuf(fd_type && fd, size_type bufsize)

  Construct the buffer with file descriptor fd and get and put area size equal to bufsize.

• basic_fildesbuf(fd_type && fd)explicit

  Construct the buffer with file descriptor fd.

• basic_fildesbuf()

Overload of std::swap for basic_fildesbuf.
