All Known Implementing Classes:

NativeLink, NativeLink
```
public interface LinkStatus
```
A class providing information about the linking status of a native library (whether it was loaded successfully, its required and actual version numbers, etc.)
The status of a library used by a particular Cryptix class can be found by calling the static method getLinkStatus() on that class.

`java.lang.String`	`getLibraryName()` Returns the library name.
`java.lang.String`	`getLinkErrorString()` Returns an error string describing why the library failed to load, or null if there was no error.
`int`	`getMajorVersion()` Returns the actual major version number.
`int`	`getMinorVersion()` Returns the actual minor version number.
`int`	`getRequiredMajorVersion()` Returns the required major version number.
`int`	`getRequiredMinorVersion()` Returns the required minor version number.
`boolean`	`isLibraryCorrect()` Returns true if the library was loaded successfully.
`boolean`	`isLibraryLoaded()` Returns true if the library was loaded.
`void`	`setNative(boolean enable)` Enables or disables the native code.

- Method Detail
  - getRequiredMajorVersion
```
int getRequiredMajorVersion()
```
    Returns the required major version number.
  - getRequiredMinorVersion
```
int getRequiredMinorVersion()
```
    Returns the required minor version number.
  - getLibraryName
```
java.lang.String getLibraryName()
```
    Returns the library name.
  - getMajorVersion
```
int getMajorVersion()
```
    Returns the actual major version number.
  - getMinorVersion
```
int getMinorVersion()
```
    Returns the actual minor version number.
  - isLibraryLoaded
```
boolean isLibraryLoaded()
```
    Returns true if the library was loaded. It may or may not be the correct version.
  - isLibraryCorrect
```
boolean isLibraryCorrect()
```
    Returns true if the library was loaded successfully.
  - useNative
```
boolean useNative()
```
    Returns true if native code is being used.
  - getLinkErrorString
```
java.lang.String getLinkErrorString()
```
    Returns an error string describing why the library failed to load, or null if there was no error.
    
    Returns:
    
    the error string, or null if no error occured
  - checkNative
```
void checkNative()
          throws java.lang.UnsatisfiedLinkError
```
    Checks that the native library is being used (i.e. it loaded successfully, has valid version numbers, and has not been disabled).
    
    Throws:
    
    java.lang.UnsatisfiedLinkError - if the library is not being used
  - setNative
```
void setNative(boolean enable)
```
    Enables or disables the native code. By default, native code is used whenever its library can be loaded correctly. This method can be used to disable native linking (and re-enable it) for a specific class.
    
    Parameters:
    
    enable - true if native code should be used.
