Echo Justin's comment that what you want to do is very unusual.. as pretty much everything you can do in Pro*C, can these days be done using PL/SQL inside Oracle.. so why then, from PL/SQL, call Pro*C?
Besides the options listed by Justin, there's also EXT PROC that allows the definition of external procedures. In this case the Pro*C code needs to be shared object/dynamic link library.
