event_groups.h

   void xEventGroupDelete( EventGroupHandle_t xEventGroup );

Delete an event group that was previously created by a call to xEventGroupCreate(). Tasks that are blocked on the event group will be unblocked and obtain 0 as the event group's value.

Parameters

xEventGroup

The event group being deleted.
