NAME

       votequorum_dispatch - Dispatches callbacks from the votequorum service

SYNOPSIS

       #include <corosync/votequorum.h>

       int votequorum_dispatch(votequorum_handle_t handle, cs_dispatch_flags_t *dispatch_types);

DESCRIPTION

       The votequorum_dispatch function is used to dispatch configuration changes.

       Each  application  may  have  several connections to the votequorum 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 = 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_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

       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 interrupted by a signal

       CS_ERR_NOT_SUPPORTED The requested protocol/functionality not supported

       CS_ERR_MESSAGE_ERROR Incorrect auth message received

       CS_ERR_NO_MEMORY Not enough memory to complete the requested task
