QUORUM_DISPATCH(3)Corosync Cluster Engine Programmer's ManuaQUORUM_DISPATCH(3)

NAME
       quorum_dispatch - Dispatches callbacks from the quorum service

SYNOPSIS
       #include	<corosync/quorum.h>

       int  quorum_dispatch(quorum_handle_t  handle, cs_dispatch_flags_t *dis-
       patch_types);

DESCRIPTION
       The quorum_dispatch function is used to dispatch	configuration changes.

       Each application	may have several connections to	the quorum 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 = 1,
	       CS_DISPATCH_ALL = 2,
	       CS_DISPATCH_BLOCKING = 3,
	       CS_DISPATCH_ONE_NONBLOCKING = 4
       } cs_dispatch_flags_t;

       The dispatch values have	the following meanings:

       CS_DISPATCH_ONE
	      Dispatch	at  least 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 quorum_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
       CS_ERR_TRY_AGAIN	Resource temporarily unavailable

       CS_ERR_INVALID_PARAM Invalid argument

       CS_ERR_ACCESS Permission	denied

       CS_ERR_LIBRARY The connection failed

       CS_ERR_INTERRUPT	System call inturrupted	by a signal

       CS_ERR_NOT_SUPPORTED The	requested protocol/functuality not supported

       CS_ERR_MESSAGE_ERROR Incorrect auth message received

       CS_ERR_NO_MEMORY	Not enough memory to completed the requested task
