What is the differnce between Global Variable and Global static variable

Even though I'm pretty damned sure this has to be covered in a FAQ somewhere, I can't sleep, so here's an answer:

A global variable is a variable that is accessable by any function in the file.

A static variable (of any kind) is one that is unchangeable.

Actually, here's the difference:

Global Variable-- can be accessed by any other function, across any number of source files, requires 'extern' referencing.

Static Global Variable-- Can be access by any functions _within_ the file it's in. Cannot be accessed from other sourcefiles.

enjoy.

Ahhhhh, that's what those are!! GEEEEZZ, i feel sooo much relief!! ahhhhh yessssss the coooool airrr and breeezee.. i need a coffee.

A global variable is an event somewhere in the world that everyone hears about in the newspaper the next morning, whereas a static global variable is responsible for all that fuzz on the tv screen channels before you hook up the cable line.
