Roaraudio sound library
#include <roaraudio.h>
libroar is a central library used to comunicate with RoarAudio servers. It supports all commands from simple commands to play some audio up to complex commands to controll the server and do nice things over the network. It also includes several useful functions from buffer mangement to IO abstraction.
The basic tools shiped with RoarAudio are designed to also work as examples for the lib. You may start by looking at roarcat(1)s source code as an example on how to simply play back some audio. A more complex example is roarvorbis(1) which also includes meta data updates.
You should also have a look at VS API, see roarvs(7) for a overview.
Tutorials can be found in roartut(7).
The following variables are used in libroar itself so they are common to all clients using libroar.
HOME
The users home directory.
ROAR_SERVER
The address of the listening server. This may be in form of host:port for TCP/IP connections and /path/to/sock for UNIX Domain Sockets. If a value of '+fork' is given a roard is forked and used. This roard will not listen on any sockets so it is used exclusiv by this client. See roard(1) for more information.
ROAR_PROXY
Set the type of the proxy being used to connect to the server. Valid values are 'socks4', 'socks4a', 'socks4d', 'http' and 'ssh' for the moment. You can add type depending options in form 'type/opts'.
socks_proxy
The SOCKS4/4a/4d/5 proxy to use in form [user@]host[:port]. Default port is 9050.
http_proxy, https_proxy
The HTTP/HTTPS Proxy server. This server needs to understand the CONNECT request type. Give the server name in this format: [http://]host[:port][/] The default port is 8080.
ssh_proxy
The remote host to use as SSH Proxy server. Give the server name in this format: [user@]host[:port] The default port is 22. Note that you may need to use publickey based auth or ssh-agent because the application may start SSH in a non interactive environment and SSH can not ask you for a password.
/etc/roarserver
This is a symlink to the server socket. If all types of server addresses are supported. Example: ln -s /tmp/roar /etc/roarserver ln -s somehost /etc/roarserver ln -s mynode:: /etc/roarserver
