CMAP_DISPATCH(3) Corosync Cluster Engine Programmer's Manual CMAP_DISPATCH(3) NAME 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 dis- patch_types); DESCRIPTION The cmap_dispatch function is used to dispatch configuration changes. Each application may have several connections to the CMAP API. Each appli- cation uses the handle argument to uniquely identify the connection. The dispatch_types argument is used to identify the type of dispatch to ex- ecute. The possible types are CS_DISPATCH_ONE, CS_DISPATCH_ALL and CS_DIS- PATCH_BLOCKING. The dispatch values have the following meanings: CS_DISPATCH_ONE Dispatch at least one callback, blocking until the callback is dis- patched. 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 re- turned.
