CPG_DISPATCH(3)	  Corosync Cluster Engine Programmer's Manual  CPG_DISPATCH(3)

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 connec‐
       tion.

       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_dis‐
	      patch() 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.
