Synopsis

unsigned ctl_events_wait(CTL_EVENT_WAIT_TYPE_t type,
                         CTL_EVENT_SET_t *eventSet,
                         CTL_EVENT_SET_t events,
                         CTL_TIMEOUT_t t,
                         CTL_TIME_t timeout);

Description

ctl_events_wait waits for events to be set (value 1) in the event set pointed to by eventSet with an optional timeout applied if timeoutType is non-zero.

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 returns the value pointed to by eventSet before any auto-clearing occurred or zero if the timeout occurred.

Note

ctl_events_wait must not be called from an interrupt service routine.
