Synopsis

unsigned ctl_events_wait_nb(CTL_EVENT_WAIT_TYPE_t waitType,
                            CTL_EVENT_SET_t *eventSet,
                            CTL_EVENT_SET_t events);

Description

ctl_events_wait_nb waits for events to be set (value 1) in the event set pointed to by eventSet without blocking.

The waitType can be one of:

• CTL_EVENT_WAIT_ANY_EVENTS — wait for any of events in eventSet to be set.
• CTL_EVENT_WAIT_ANY_EVENTS_WITH_AUTO_CLEAR — wait for any of events in eventSet to be set and reset (clear) them.
• CTL_EVENT_WAIT_ALL_EVENTS — wait for all events in eventSet to be set.
• CTL_EVENT_WAIT_ALL_EVENTS_WITH_AUTO_CLEAR — wait for all events in eventSet to be set and reset (clear) them.

ctl_events_wait_nb returns the value pointed to by eventSet before any auto-clearing occurred.

Note

ctl_events_wait_nb must not be called from an interrupt service routine.
