I am confused about the operation of the Native rt_event_bind()
function and I have not found any example of its use.
The documentation states...
int rt_event_bind (RT_EVENT * event, const char * name, RTIME timeout)
Parameters:
...
event The address of an event flag group descriptor retrieved by the
operation. Contents of
this memory is undefined upon failure.
...
Is the user-space task supposed to provide memory for the RT_EVENT, ...
example:
RT_EVENT event_structure;
...
rt_event_bind (&event_structure,...)
Or, does the user-space program just provide a pointer variable to
retain the event structure provided to it by the function?
example:
RT_EVENT *event_pointer;
...
rt_event_bind (event_pointer,...)
Neither seems to work correctly, the former only allocates a word of memory.
printf("sizeof(event_structure)=%d", sizeof(event_structure) );
Prints 4. This seems too small.
The latter fails with an error code -14 (EFAULT).
Regards,
Bob Feretich
