No it isn't.
1) It may fail with overflow errors
2) Calling this in a program WON'T ACTUALLY SWAP ANYTHING the calling
code wants it to.
Read <http://tech.groups.yahoo.com/group/c-prog/files/html/swapnotemp.html>
(or <http://avsharath.googlepages.com/swapnotemp.html> if you can't
get the first copy) LIKE YOU WERE TOLD TO DO AT THE TOP OF THE THREAD!
