Traits that abstract read and write operations for stream buffers.

• With this class it is possible to plug arbitrary object (including another stream buffer) as a source or sink for stream buffer using basic_fildesbuf.
• Generic implementation is done for std::streambuf.

Types

• using char_type = T::char_type

  Character type.

Methods

• in_avail(T & buf) -> std::streamsize

  Check how many bytes are available for reading in buffer buf.

• is_blocking(const T &) -> bool

  Check if the source/sink is blocking.

• read(T & buf, char_type * s, std::streamsize n) -> std::streamsize

  Read n bytes to array pointed by s from buffer buf.

• write(T & buf, const char_type * s, std::streamsize n) -> std::streamsize

  Write n bytes from array pointed by s to buffer buf.
