All functions in the C language can be prototyped, whether ISO/ANSI 
or POSIX has given them their blessing or not.  My headers on a SVR4 
Unix have both prototypes and no prototypes, namely:

#ifdef __STDC__  /* <--the traditional macro for ANSI C-conforming 
code */
unsigned myprototypedfunction(int, int, struct dumb *);
#else
unsigned myrealKandRfunction();
#endif

And this goes for all the functions in all the libraries this system 
offers.  I have come to admit that function prototyping is the one 
useful thing ANSI C took from C++, but I insist on *defining* my 
functions with old-style parameter lists, and only the most worthless 
compilers will refuse to accept such a style.
