CPG_OVERVIEW(8)	  Corosync Cluster Engine Programmer's Manual  CPG_OVERVIEW(8)

NAME
       cpg_overview - CPG library overview

OVERVIEW
       The  CPG	 library is delivered with the corosync project.  This library
       is used to create distributed applications that operate properly during
       cluster partitions, merges, and faults.

       The library provides a mechanism to:

       *  handle  abstraction  for  multiple instances of a CPG library in one
       application

       * join one or more groups

       * leave one or more groups

       * Deliver messages to members of that group

       * Deliver configuration changes

       * Iterate members of groups

SECURITY
       If encryption is enabled in corosync.conf, the CPG library will encrypt
       and  authenticate  message  contents.  Applications must run as the ais
       user to be validated by corosync on IPC connection, otherwise they will
       be unable to access the corosync services.
