If you want to buy a book, you can buy the standard or use the draft.
The standard is available for $18USD at
http://webstore.ansi.org/ansidocstore/default.asp
the draft is available for free at:
http://www.open-std.org/JTC1/SC22/WG14/
and O'REILLY has
C Pocket Reference
which also covers C99.
The best tutorial is still
"The C Programming Lanaguage 2nd Ed" by K&R.
even though it doesn't cover up to C99.
Cheers,

The O'Reilly Pocket reference isn't bad but some of what it covers is
pre-C99 and this is not distinguished in the text which can be
confusing, I don't recommend it. It certainly isn't a complete
reference either (hence 'pocket reference').
The C99 standard will of course cover everything, you can get a fully
bookmarked pdf version for $18 online.
The book "C, A Reference Manual - 5th edition" is highly recommended.
It is a very well written, complete and concise reference to the C99
standard and also covers C89 and traditional C.
