Hi rtel,

it is defined in the cmsis_os2.c:

uint32_t osEventFlagsSet (osEventFlagsId_t ef_id, uint32_t flags) {
EventGroupHandle_t hEventGroup = (EventGroupHandle_t)ef_id;
uint32_t rflags;
BaseType_t yield;

if ((hEventGroup == NULL) || ((flags & EVENT_FLAGS_INVALID_BITS) != 0U)) {
rflags = (uint32_t)osErrorParameter;
}
else if (IS_IRQ()) {
#if (configUSE_OS2_EVENTFLAGS_FROM_ISR == 0)
(void)yield;
/* Enable timers and xTimerPendFunctionCall function to support osEventFlagsSet from ISR */
rflags = (uint32_t)osErrorResource;
#else
yield = pdFALSE;

if (xEventGroupSetBitsFromISR (hEventGroup, (EventBits_t)flags, &yield) == pdFAIL) {
  rflags = (uint32_t)osErrorResource;
} else {
  rflags = flags;
  portYIELD_FROM_ISR (yield);
}

#endif
}
else {
rflags = xEventGroupSetBits (hEventGroup, (EventBits_t)flags);
}

return (rflags);
}
