The safety library can be used in two modes: The normal mode and the wrapper mode.
In the recommended normal mode, the safety library is a library like all others.
Programm should only call the wrapped functions instead of the standard C library (or math) functions.
The second mode, the wrapper-mode, can be used with existing code.
By automatically wrapping all existing calls, the CLW can be used, without having to manually modify all code. Recompiling will be sufficient in this case.
