assertCallSucceeded

public static final void assertCallSucceeded(String message,
                                             boolean result)
                                      throws IOException

Checks if the API call result is true. If not, then calls Kernel32.GetLastError() and fails with the error code. Note: if the error code is WinError.ERROR_SUCCESS then an "unknown reason code" is reported

Parameters:

message - Message to display if call failed

result - The API call result

Throws:

IOException

assertValidHandle

public static final com.sun.jna.platform.win32.WinNT.HANDLE assertValidHandle(String message,
                                                                              com.sun.jna.platform.win32.WinNT.HANDLE handle)
                                                                       throws IOException

Makes sure that the handle argument is not null or WinBase.INVALID_HANDLE_VALUE. If invalid handle detected, then it invokes Kernel32.GetLastError() in order to display the error code

Parameters:

message - Message to display if bad handle

handle - The WinNT.HANDLE to test

Returns:

The same as the input handle if good handle - otherwise does not return and throws an assertion error

Throws:

IOException

assertEquals

protected void assertEquals(String message,
                            int len,
                            int value)
                     throws IOException

Throws:

IOException
