excellent setjmp/longjmp tutorials [closed]

Question

Hi I'd like to read good tutorials on setjmp/longjmp in C. It'd be better if there're examples which are real rather than artificial.

Thanks.

Answer 1

It's not really a tutorial as such, but the libpng documentation describes how the library uses setjmp/longjmp to do error handling.

Answer 2

The book "C interfaces and implementation" explains the concept well and implements a usable "exception" simulation in C using these constructs. The code for it (chapter 4) is freely available online here.
