Example 1 with SP_DEVINFO_DATA

use of com.sun.jna.platform.win32.SetupApi.SP_DEVINFO_DATA in project jna by java-native-access.

the class SetupApiTest method testSetupDiEnumDeviceInfo.

/**
	 * Tests the mapping of {@link SetupApi#SetupDiEnumDeviceInfo(HANDLE, int, SP_DEVINFO_DATA)} .
	 * <p>
	 * There are 2 different results possible, depending availability of an COM-Port on the current machine:
	 * <ul>
	 * <li>If the current machine has no COM-Port the method must fail and the the last error indicate that there are no more values / COM-Ports.
	 * <li>If the current machine has at least one COM-Port the method must succeed. The test pass if no exception is thrown.
	 * </ul>
