...
- The source code is not significantly larger because the function signatures do not change, and neither do functions that neither detect nor handle the error.
- Allocated resources must still be freed despite the error.
- The application must call
setjmp()before invoking application-independent code. - Signals are not necessarily preserved through
longjmp()calls. - The use of
setjmp()/longjmp()bypasses the normal function call and return discipline. - Any function that allocates resources must ensure they are freed in cases where errors occur.
