Typesage linkage enforces the right number and type of parameters are passed at link time.

For example, in C, you can define a library function as taking an int, but thru a series of mishaps, you can pass it a string.

C++ avoids this kind of error by making function prototypes mandatory and my using name mangling to enforce typesafe linking.
