C++ include files description

[Marco Marchi]

Hi,
I'm developing under C++ and I obviously need to use library functions.
Can anybody tell me where I can find a full description of standard ANSI
C++ include functions, their scope and their syntax?
I have some documentation but it ins't complete: I think that reading
all inlcude files contents would be extremely time consuming and not at
all exhaustive.    What I'm looking for is a simple guide
with syntax description.
If anyone of you knows some reference about sites or books, please mail
me back to:
dwarf@katamail.com
or
marchi@sistemi-integrati.com
Thank you
