`gpio.h` only sets a snapshot of the GPIO state. I doesn't program any additional logic. All GPIOs that need to change its state during runtime need additional programming, either in C or ASL (ACPI). I suggest to decode the changing GPIO registers, if you haven't already. Some may be configured as inputs and might only change state as a result of other changes...
