Function esp_idf_sys::esp_http_client_flush_response

pub unsafe extern "C" fn esp_http_client_flush_response(
    client: esp_http_client_handle_t,
    len: *mut c_int,
) -> esp_err_t

@brief Process all remaining response data This uses an internal buffer to repeatedly receive, parse, and discard response data until complete data is processed. As no additional user-supplied buffer is required, this may be preferable to esp_http_client_read_response in situations where the content of the response may be ignored.

@param[in] client The esp_http_client handle @param len Length of data discarded

@return - ESP_OK If successful, len will have discarded length - ESP_FAIL If failed to read response - ESP_ERR_INVALID_ARG If the client is NULL
