NAME

       cpg_local_get - Returns the local node id

SYNOPSIS

       #include <corosync/cpg.h>

       int cpg_local_get(cpg_handle_t handle, unsigned int *local_nodeid);

DESCRIPTION

       The  cpg_local_get function is used to determine the local node's identifier.   The argument handle is used to reference the cpg instantia-
       tion.  The argument local_nodeid will return the 32 bit node id.

ERRORS

       The errors are undocumented.

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.
