NAME¶

roar_socket_listen - Opens a new listen socket

SYNOPSIS¶

#include <roaraudio.h>

int roar_socket_listen(int type, char * host, int port);

DESCRIPTION¶

Opens a new listening socket for network clients to connect to. You may accept new connections via accept(2).

PARAMETERS¶

type

The type of the Socket. See the list below.

host

The host or path name to listen on. This depends on the type argument. For TCP/IP to listen on any interface use a value of "0.0.0.0".

port

The port number to listen on. This may be ignored by types not supporting port numbers.

SOCKET TYPES¶

ROAR_SOCKET_TYPE_UNKNOWN

The type will be auto detected. Don't use this if you know the type. Only use this to support user given addresses and enable auto detection.

ROAR_SOCKET_TYPE_TCP

Use a TCP/IP connection. This is standard mode for networking. host is the hostname or IP to listen on and port is the port number to use.

ROAR_SOCKET_TYPE_INET

Same as above but deprecated. Use ROAR_SOCKET_TYPE_TCP.

ROAR_SOCKET_TYPE_UNIX

UNIX Domain Socket. This should be default for local connections. host is the filename of the socket.

ROAR_SOCKET_TYPE_DECNET

DECnet socket.

ROAR_SOCKET_TYPE_FORK

This is to fork a roard to communicate with. Can't be use to listen on, just to connect to. host and port is ignored at the moment.

ROAR_SOCKET_TYPE_FILE

This is used to open a plain file. Can't be use to listen on, just to connect to. host is the filename to connect to.

RETURN VALUE¶

On success these calls return filehandle. On error, -1 is returned.

BUGS¶

Listening on UDP sockets is not supported at the moment.
