How to use the pysurvive.configf function in pysurvive

def plot_imu(self, fig = None, plot_num = 1, plot_rows = 2, plot_cols = 2, figsize=None, **kwargs):
        if fig is None:
            fig = plt.figure(figsize=figsize)

        ax = fig.add_subplot(plot_rows, plot_cols, plot_num, title=self.name + ' Gyros')

        moveThreshGyro = pysurvive.configf(self.so.contents.ctx, "move-threshold-gyro", pysurvive.SC_GET, 0)
        moveThreshAcc = pysurvive.configf(self.so.contents.ctx, "move-threshold-acc", pysurvive.SC_GET, 0)

        axes_name = ['X', 'Y', 'Z']
        gyros = np.array(self.gyros)
        ax.plot([self.imu_times[0],self.imu_times[-1]], [moveThreshGyro] * 2, linewidth=1)
        ax.plot(self.imu_times, np.linalg.norm(gyros, axis=1), linewidth=1, label='Norm')
        for i in range(3):
            ax.plot(self.imu_times, gyros[:, i], linewidth=1, label=axes_name[i])
        ax.legend()

        ax = fig.add_subplot(plot_rows, plot_cols, plot_num + 1, title=self.name + ' Accels')

        ax.plot([self.imu_times[0],self.imu_times[-1]], [moveThreshAcc] * 2, linewidth=1)
        ax.plot(self.imu_times[1:], np.linalg.norm(np.diff(self.accels, axis=0), axis=1), linewidth=1)
