Implementation of the claw::net::basic_isocket_stream class.
traits_type::int_type int_type
The type used to represent integers.
A class to use any socket as a classic standard input stream.
Traits traits_type
The traits carry some informations about the char_type.
bool is_open() const
Tell if the stream is open.
buffer_type * rdbuf() const
Get the input buffer.
traits_type::pos_type pos_type
The type used to represent a position in the stream.
void close()
Close the connection.
basic_isocket_stream< char > isocket_stream
Implementation of the basic_isocket_stream for the char type.
Socket buffer to be used with std::basic_socket_stream, for easy socket reading and writing...
CharT char_type
The type of the characters in the stream.
basic_socketbuf< char_type, traits_type > buffer_type
The type of the buffer manipulated by this stream.
void open(const std::string &address, int port)
Connect the socket to an address.
traits_type::off_type off_type
The type used to represent a delta in the positions.
basic_isocket_stream< wchar_t > wisocket_stream
Implementation of the basic_isocket_stream for the wide characters.
