Function esp_idf_svc::hal::sys::esp_flash_get_protected_region

pub unsafe extern "C" fn esp_flash_get_protected_region(
    chip: *mut esp_flash_t,
    region: *const esp_flash_region_t,
    out_protected: *mut bool,
) -> i32

@brief Detect if a region of the SPI flash chip is protected

@param chip Pointer to identify flash chip. Must have been successfully initialised via esp_flash_init() @param region Pointer to a struct describing a protected region. This must match one of the regions returned from esp_flash_get_protectable_regions(…). @param[out] out_protected Pointer to a flag which is set based on the protected status for this region.

@note It is possible for this result to be false and write operations to still fail, if protection is enabled for the entire chip.

@note Correct behaviour of this function depends on the SPI flash chip model and chip_drv in use (via the ‘chip->drv’ field).

@return ESP_OK on success, or a flash error code if operation failed.
