So I've just learned that C has no exceptions

Instead, they use some weird setjmp/longjmp shit.
Holy fuck, and some trolls here dare say that "C is a good language".

procedures are an adequate abstraction for exception handling

Adequate, yes. Ideal, no.

In the general case, handling error conditions requiring early termination of a procedure in C involves either deeply nesting conditionals, returning early, or using goto. Many compilers generate bad code for early returns, so if you are really concerned about performance and want to avoid nesting you are suck with goto.
