NAME

       cpg_dispatch - Dispatches callbacks from the CPG service

SYNOPSIS

       #include <corosync/cpg.h>

       int cpg_dispatch(cpg_handle_t handle, cpg_dispatch_t *dispatch_types);

DESCRIPTION

       The  cpg_dispatch  function is used to dispatch configuration changes or messages from the
       closed process groups API.

       Each application may have several connections to the CPG API.  Each application  uses  the
       handle argument to uniquely identify the connection.

       The  dispatch_types  argument  is  used  to identify the type of dispatch to execute.  The
       possible types are defined by the structure:

              typedef enum {
                      CS_DISPATCH_ONE,
                      CS_DISPATCH_ALL,
                      CS_DISPATCH_BLOCKING
              } cpg_dispatch_t;

       The dispatch values have the following meanings:

       CS_DISPATCH_ONE
              Dispatch atleast one callback, blocking until the callback is dispatched.

       CS_DISPATCH_ALL
              Dispatch all waiting callbacks without blocking to wait for any callbacks.

       CS_DISPATCH_BLOCKING
              Dispatch all callbacks, blocking indefinitely.  This is used in a threaded  program
              where  a  thread is created, and then cpg_dispatch() is called immediately from the
              created thread to execute callbacks.

       CS_DISPATCH_ONE_NONBLOCKING
              Dispatch at most one callback. If there is no pending callback, CS_ERR_TRY_AGAIN is
              returned.

RETURN VALUE

       This call returns the CS_OK value if successful, otherwise an error is returned.

ERRORS

       The errors are undocumented.
