◆ gpio_fire_callbacks()
Generic function to go through and fire callback from a callback list.
- Parameters
-
list | A pointer on the gpio callback list |
port | A pointer on the gpio driver instance |
pins | The actual pin mask that triggered the interrupt |
◆ gpio_manage_callback()
Generic function to insert or remove a callback from a callback list.
- Parameters
-
callbacks | A pointer to the original list of callbacks (can be NULL) |
callback | A pointer of the callback to insert or remove from the list |
set | A boolean indicating insertion or removal of the callback |
- Returns
- 0 on success, negative errno otherwise.
