xEventGroupGetBits()
[Event Group API]



event_groups.h 

 EventBits_t xEventGroupGetBits( EventGroupHandle_t xEventGroup );

The RTOS source file FreeRTOS/source/event_groups.c must be included in the build for the xEventGroupGetBits() function to be available.

Parameters:
xEventGroup   The event group being queried. The event group must have previously been created using a call to xEventGroupCreate().
Returns:
The value of the event bits in the event group at the time xEventGroupGetBits() was called.
