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

they are used to implement coroutines. There are a couple of c++ coroutine libraries running around on the net, that in Unix/Linux will use setjmp/longjmp to implement the functionality.

So, if your goal is to implement a coroutine library, then it is a moot point if its good practice or not, since on those platforms it is the only way to support that functionality.

if your goal is to use a coroutine library, you should search for some of these instead. There is even a boost vault proposal called boost::context, which is already approved.
