Example 1 with TOKEN_PRIVILEGES

use of com.sun.jna.platform.win32.WinNT.TOKEN_PRIVILEGES in project jna by java-native-access.

the class Advapi32Test method testAdjustTokenPrivileges.

public void testAdjustTokenPrivileges() {
    HANDLEByReference hToken = new HANDLEByReference();
    assertTrue(Advapi32.INSTANCE.OpenProcessToken(Kernel32.INSTANCE.GetCurrentProcess(), WinNT.TOKEN_ADJUST_PRIVILEGES | WinNT.TOKEN_QUERY, hToken));
    try {
        // Find an already enabled privilege
        TOKEN_PRIVILEGES tp = new TOKEN_PRIVILEGES(1024);
        IntByReference returnLength = new IntByReference();
        assertTrue(Advapi32.INSTANCE.GetTokenInformation(hToken.getValue(), WinNT.TOKEN_INFORMATION_CLASS.TokenPrivileges, tp, tp.size(), returnLength));

            }
        }
        assertTrue(luid != null);
        // Re-enable it. That should succeed.
