pub unsafe extern "C" fn rtc_gpio_force_hold_en_all() -> esp_err_t

@brief Enable force hold signal for all RTC IOs

Each RTC pad has a “force hold” input signal from the RTC controller. If this signal is set, pad latches current values of input enable, function, output enable, and other signals which come from the RTC mux. Force hold signal is enabled before going into deep sleep for pins which are used for EXT1 wakeup.
