While cruising through my white book the other day, I noticed in the list of C keywords. entry is one of the keywords on that list.
It is reserved for future use. Thinking back to my Fortran days, there was a function of some sort that used an entry statement to make a second argument signature, or entry point into a function.
Is this what entry was originally intended to be used for? or something completely different?
What is the story on the entry keyword?
I had no idea, so I googled to find something about this. This is what I found.
First, it was included as a reserved keyword.
(From http://archives.devshed.com/forums/c-c-134/c-programming-faqs-371017.html.)
It was never standardized; some compilers used it, in a very personal way.
It was later declared obsolete, I guess.
