Hi
The below from my Qt HAL access libraries demonstrates a way to access
components.
Note that the pointer is passed and from that the name is read, so you
have all you need once you find the right one.
regards
void HAL_Access::getAllComponentNames(QStringList& list)
{
int next;
hal_comp_t *comp;
rtapi_mutex_get(&(hal_data->mutex));
next = hal_data->comp_list_ptr;
while (next != 0)
{
comp = (hal_comp_t *)SHMPTR(next);
list.append(comp->name);
next = comp->next_ptr;
}
rtapi_mutex_give(&(hal_data->mutex));
}
