peter,

i agree that c programmers may be attracted to reentrant functions for silly reasons; i don't hire any c programmers for microprocessor work due to my opposition to this enabler of sloppy coding.

however, reentrant code is a necessary construct in many advanced applications most commonly understood being tree traversal algorithms. maybe its just my training in operations research (algorithms) that makes me crazy enough to use them in microprocessors.

there are ways of unfolding even reentrant functions supporting data structures so that no stack is used, but i don't post those secrets on any forum; those are earned in the classroom. :)

duh - c belongs on PCs only
