Examples with NativeLongByReference com.sun.jna.ptr.NativeLongByReference used on opensource projects

Example 1 with NativeLongByReference

use of com.sun.jna.ptr.NativeLongByReference in project jna by java-native-access.

the class ByReferenceArgumentsTest method testNativeLongByReference.

public void testNativeLongByReference() {
    NativeLongByReference iref = new NativeLongByReference();
    lib.incrementNativeLongByReference(iref);
    assertEquals("Native long argument not modified", new NativeLong(1), iref.getValue());
}

Example 2 with NativeLongByReference

use of com.sun.jna.ptr.NativeLongByReference in project HearthStats.net-Uploader by HearthStats.

the class ProgramHelperOsx method findWindow.

/**
     * <p>Finds the main Hearthstone window ID for the given process ID.</p>
     * <p>Will only return the window that matches expected characteristics of the main Hearthstone window, namely:</p>
     * <ul>
     *     <li>kCGWindowIsOnscreen = 1</li>
     *     <li>kCGWindowLayer = 0</li>
     *     <li>kCGWindowOwnerPID = [pid]</li>
     * </ul>
     *
     * @param pid The process ID of Hearthstone.
     * @return the window ID if found, or zero if no suitable window was found. It is normal for the window ID to be zero briefly during startup of Hearthstone.
