NAME

       votequorum_fd_get - Dispatches callbacks from the votequorum service

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_fd_get(votequorum_handle_t handle, int *fd);

DESCRIPTION

       The  votequorum_fd_get  function is used to retrieve the file descriptor that may be used with the poll system call to determine when vote-
       quorum_dispatch(3) won't block.	The handle argument may not be used directly with poll because it is not the file descriptor, but  instead
       an internal identifier used by the votequorum library.

RETURN VALUE

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

ERRORS

       The errors are undocumented.

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

NAME

       votequorum_initialize - Create a new connection to the VoteQuorum service

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_initialize(votequorum_handle_t *handle, votequorum_callbacks_t *callbacks);

DESCRIPTION

       The votequorum_initialize function is used to initialize a connection to the vote-based quorum database API.

       Each  application  may  have several connections to the votequorum API.	Each application uses the handle argument to uniquely identify the
       connection.  The handle argument is then used in other function calls to identify the connection to be  used  for  communication  with  the
       votequorum service.

       Every  time  the  voting  configuraton  changes	(eg  a node joins or leave the cluster), the callback is called.  The callback function is
       described by the following type definitions:

       typedef void (*votequorum_notification_fn_t) (	   votequorum_handle_t handle,	    uint64_t context,	   uint32_t quorate,	  uint32_t
       node_list_entries,      votequorum_node_t node_list[]	  );

       The callbacks argument is of the type:

	      typedef struct {
	      votequorum_notification_fn_t votequorum_notify_fn;
	      } votequorum_callbacks_t;

       When a configuration change occurs, the callback is called from the votequorum_dispatch() function.

RETURN VALUE

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

BUGS

       Callbacks are not support at the moment.

ERRORS

       The errors are undocumented.
