Calvin: Do we have any chainsaws in the house?
His Mother: No.
Calvin: Then how am I supposed to learn to juggle?

Sokar has asked how to do something that is almost
certainly better not done. Other points in his question
suggest he's not an experienced C juggler, certainly not
ready for the perils of longjmp(). Find out what he's
trying to do, not what he's asking: there's very likely
a better (and easier) way to get to his real goal.

But unless you like watching involuntary amputations,
please don't tell him where the chainsaws are.
