New Revision: 368673

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=368673
Log:
Fix reloading an unchanged file with the Config Options API

Adding multiple file support broke reloading an unchanged file. This
adds an enum for return values for the aco_process_* functions and
ensures that the config is not applied if res is not ACO_PROCESS_OK.
