20 The rsm_intr_signal_post() and rsm_intr_signal_wait() functions are
21 event functions that allow synchronization between importer processes
22 and exporter processes. A process may block to wait for an event occu‐
23 rance by calling rsm_intr_signal_wait(). A process can signal a waiting
24 process when an event occurs by calling rsm_intr_signal_post().
25
26
27 The rsm_intr_signal_post() function signals an event occurance. Either
28 an import segment handle (rsm_memseg_import_handle_t) or an export seg‐
29 ment handle (rsm_memseg_export_handle_t) may be type cast to a void
30 pointer for the memseg argument. If memseg refers to an import handle,
31 the exporting process is signalled. If memseg refers to an export han‐
32 dle, all importers of that segment are signalled. The flags argument
33 may be set to RSM_SIGPOST_NO_ACCUMULATE; this will cause this event to
34 be discarded if an event is already pending for the target segment.
35
36
37 The rsm_intr_signal_wait() function allows a process to block and wait
38 for an event occurance. Either an import segment handle (rsm_mem‐
39 seg_import_handle_t) or an export segment handle (rsm_mem‐
40 seg_export_handle_t) may be type cast to a void pointer for the memseg
41 argument. The process blocks for up to timeout milliseconds for an
42 event to occur; if the timeout value is -1, the process blocks until an
43 event occurs or until interrupted.

46 Upon successful completion, these functions return 0. Otherwise, an
47 error value is returned to indicate the error.
