Member Function Documentation

accept() [1/2]

virtual std::unique_ptr< Socket > tenduke::osa::Socket::accept ( )

pure virtual

Accepts next connection from listening socket.

No timeout.

Returns

the child socket

accept() [2/2]

virtual std::unique_ptr< Socket > tenduke::osa::Socket::accept ( uint32_t timeoutMs )

pure virtual

Accepts next connection from listening socket, with a timeout.

The socket must be set to listening mode using listen() before calling this method. New connection is returned as new tenduke::osa::Socket. This method times out after timeoutMs milliseconds and then returns nullptr.

IMPORTANT NOTE: When using timeout, you should call setNonBlocking() on the socket to avoid race conditions.

Parameters

timeoutMs

timeout in milliseconds. Zero timeout is not yet supported.

Returns

the child socket or nullptr if accept timed out

Exceptions

tenduke::net::NetworkingException

in any case of error

getPort()

virtual std::uint16_t tenduke::osa::Socket::getPort ( ) const

pure virtual

Returns port of the socket.

Returns

the port number

listen()

virtual void tenduke::osa::Socket::listen ( )

pure virtual

Configures the socket to listen for incoming connections.

Exceptions

tenduke::net::NetworkingException

in any case of error

read()

virtual int tenduke::osa::Socket::read ( void * buffer, std::size_t bufferSize )

pure virtual

Reads bytes from the socket.

Parameters

buffer	buffer where the bytes are placed to
bufferSize	size of the buffer in bytes

Returns

number of bytes read. Returns -1, if socket is non-blocking and nothing to read yet.

Exceptions

tenduke::net::NetworkingException

in any case of error

setNonBlocking()

virtual void tenduke::osa::Socket::setNonBlocking ( )

pure virtual

Sets the socket to non-blocking mode.

Exceptions

tenduke::net::NetworkingException

in any case of error

write()

virtual int tenduke::osa::Socket::write ( const void * buffer, std::size_t len )

pure virtual

Write bytes to the socket.

Parameters

buffer	these bytes are written
len	number of bytes to write

Returns

number of bytes written

Exceptions

tenduke::net::NetworkingException

in any case of error
