Inheritance diagram for cgv::os::socket_server:

Public Member Functions
bool	bind_and_listen (int port, int max_nr_pending_connections)
	bind and listen to given port with a queue for pending connections of the given size

socket_ptr	wait_for_connection ()
	if no connection is pending, block thread and wait for next incoming connection

socket_ptr	check_for_connection ()
	check if a new connection is in the connection queue and return this or an empty connection pointer

std::string	get_last_error () const
	returns the last error

bool	is_data_pending () const
	return whether data has arrived

int	get_nr_of_arrived_bytes () const
	return the number of data bytes that have been arrived at the socket or -1 if socket is not connected More...

std::string	receive_line ()
	receive data up to the next newline excluding the newline char

std::string	receive_data (unsigned int nr_of_bytes=0)
	receive all pending data or if nr_of_bytes is larger than 0, exactly nr_of_bytes

bool	send_line (const std::string &content)
	extends line by newline and send as data

bool	send_data (const std::string &)
	send the data in the string

bool	close ()
	close the socket

int	get_ref_count () const
	read access to current count

Static Public Member Functions
static void	enable_debug_output (bool enable=true)
	enables or disables (default) debug output for all socket commands

Protected Member Functions
	socket_server ()
	hide from direct use

bool	set_last_error (const char *location, const std::string &text="") const
	convenience function to set last error and print debug info. The method always returns false.

void	set_ref_count (int c) const
	write access is also const to allow ref counted pointers to const instances

Protected Attributes
size_t	user_data
	store platform dependent reference to socket

std::string	last_error
	store the last error

Friends
CGV_API socket_server_ptr	create_socket_server ()
	this is the only way to create a socket_server as a reference counted pointer
