Java Examples for com.sun.jna.platform.win32.Winsvc.SERVICE_STATUS_PROCESS

The following java examples will help you to understand the usage of com.sun.jna.platform.win32.Winsvc.SERVICE_STATUS_PROCESS. These source code samples are taken from different open source projects.

Example 1

Project: jna-mirror-master File: Advapi32Test.java View source code

public void testQueryServiceStatusEx() {
    SC_HANDLE scmHandle = Advapi32.INSTANCE.OpenSCManager(null, null, Winsvc.SC_MANAGER_CONNECT);
    assertNotNull(scmHandle);
    SC_HANDLE serviceHandle = Advapi32.INSTANCE.OpenService(scmHandle, "eventlog", Winsvc.SERVICE_QUERY_STATUS);
    assertNotNull(serviceHandle);
    IntByReference pcbBytesNeeded = new IntByReference();
    assertFalse(Advapi32.INSTANCE.QueryServiceStatusEx(serviceHandle, SC_STATUS_TYPE.SC_STATUS_PROCESS_INFO, null, 0, pcbBytesNeeded));
    assertEquals(W32Errors.ERROR_INSUFFICIENT_BUFFER, Kernel32.INSTANCE.GetLastError());
    assertTrue(pcbBytesNeeded.getValue() > 0);
    SERVICE_STATUS_PROCESS status = new SERVICE_STATUS_PROCESS(pcbBytesNeeded.getValue());
    assertTrue(Advapi32.INSTANCE.QueryServiceStatusEx(serviceHandle, SC_STATUS_TYPE.SC_STATUS_PROCESS_INFO, status, status.size(), pcbBytesNeeded));
    assertTrue(status.dwCurrentState == Winsvc.SERVICE_STOPPED || status.dwCurrentState == Winsvc.SERVICE_RUNNING);
    assertTrue(Advapi32.INSTANCE.CloseServiceHandle(serviceHandle));
    assertTrue(Advapi32.INSTANCE.CloseServiceHandle(scmHandle));
}
