Is it good programming practice to use setjmp and longjmp in C?

Question

I\'m a C++ programmer and used to OO languages with good exception handling.

From what I can understand, setjmp and longjmp are essentially a c-style way to propogate ex

Answer 1

Essentially, you're right in your assertion that jmp-style propagation is essentially the same thing as goto. Read Dijkstra's (famous and controversial) paper about gotos which (I think) provides sensible reasoning for why gotos should rarely be used. Unless you know exactly why you're doing what you're doing (or you're working in very specific fields -- such as embedded programming), you should not touch either goto or longjmp.
