Normal mode

All functions of the safety library can be called normally, like any C function. This is the mode, as the source code makes it clear the safe functions are used.

The programmer should be aware that the functions are actually macros. This macro the macros are just their for convencience. The real safety-functions have the same name as the macro, but with a additional leading underscore. E.g.

extern int _clw_unlink(const char *s);
 
#define clw_unlink( a ) _clw_unlink( (a) ))
