Query Device Caps Test (Compact 7)
3/12/2014
The Query Device Caps Test tests if the touch panel driver supports the TouchPanelGetDeviceCaps function. The test uses both the TPDC_SAMPLE_RATE_ID and TPDC_CALIBRATION_POINT_COUNT_ID flags. This test fails if the TouchPanelGetDeviceCaps function call fails with either of the specified flags. The test is skipped if the touch panel driver does not export a TouchPanelGetDeviceCaps function.
This is test 1001 in the touchfuc.dll test suite.
Note: For most tests, the touch panel driver level test requires user-interaction by using a touch pen on the touch panel. After the test is complete, the OS loses control of the touch panel.
