votequorum_dispatch - Dispatches callbacks from the votequorum service SYNOPSIS
#include <corosync/votequorum.h> int votequorum_dispatch(votequorum_handle_t handle, votequorum_dispatch_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, CS_DISPATCH_ALL, CS_DISPATCH_BLOCKING } votequorum_dispatch_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 votequo- rum_dispatch() is called immediately from the created thread to execute callbacks. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. ERRORS
The errors are undocumented. SEE ALSO

cmap_dispatch - Dispatches callbacks from the CMAP service SYNOPSIS
#include <corosync/cmap.h> cs_error_t cmap_dispatch (cmap_handle_t handle, cs_dispatch_flags_t dispatch_types); DESCRIPTION
The cmap_dispatch function is used to dispatch configuration changes. Each application may have several connections to the CMAP 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 CS_DISPATCH_ONE, CS_DISPATCH_ALL and CS_DISPATCH_BLOCKING. 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 cs_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. It's needed to call cmap_track_add(3) to add tracked items and receive callbacks. RETURN VALUE
This call returns the CS_OK value if successful, otherwise an error is returned. SEE ALSO
