[net.lang.c] What is the setjump call?

zemon@felix.UUCP (Art Zemon) (10/02/84)

The routine is "setjmp" and in conjunction with "longjmp"
provides the ability to "goto" anywhere in a program where
you have already been.  It is typically used for error
recovery or interrupt handling and, like the mundane
"goto," is probably not a part of good, structured
programming.

You certainly should not go out of your way to work it into
your programs.
