* This is a Rivendell Loadable Module. It uses Now&Next PAD data
|
||||
* to update the metadata on an Icecast2 mountpoint specified in the
|
||||
* configuration file pointed to by the plugin argument.
|
||||
*
|
||||
* This module requires the curl(1) network transfer tool, included with
|
||||
* most Linux distros. It is also available at http://curl.haxx.se/.
|
||||
*
|
||||
* To compile this module, just do:
|
||||
*
|
||||
* gcc -shared -o rlm_icecast2.rlm rlm_icecast2.c
