Reading and writing long longs

[Doug]

The Data General AViiON workstation supplies gcc as its native compiler.
One of the GNU extensions are the long long data type (64 bit ints).
The compiler seems to like them just fine, however, I can't find a way
to print them out or read them in.  A look through the man pages for
printf, scanf and the GNU gcc info files reveals nothing interesting.
Am I overlooking something?
