os_evt_get

#include <rtl.h>

U16 os_evt_get (void);

You can use the os_evt_get function to identify the event that caused the os_evt_wait_or function to complete.

The os_evt_get function identifies this event by setting the corresponding flag in the returned value. If more than one event occurred simultaneously, all their flags are set in the returned value.

The os_evt_get function is in the RL-RTX library. The prototype is defined in rtl.h.

• When the os_evt_wait_or function has been waiting on more than one event, it is not immediately known which event caused the os_evt_wait_or function to return. This is why the os_evt_get function is useful.

The os_evt_get function returns a bit pattern that identifies the events that caused the os_evt_wait_or function to complete.

os_evt_wait_or

#include <RTL.h>

__task void task1 (void) {
  U16 ret_flags;

  if (os_evt_wait_or (0x0003, 500) == OS_R_EVT) {
    ret_flags = os_evt_get ();
    printf("Events %04x received.\n",ret_flags);
  }
   ..
