This manual presents ANSI C as the standard version
of the C language. Where certain constructs are not available in compatibility
mode, or would work differently, it is noted and the differences are
described.
HP C/HP-UX, when invoked in ANSI mode, is a conforming
implementation of ANSI C, as specified by American National Standard
9899-1990. This manual uses the terminology of that standard and attempts
to explain the language defined by that standard, while also documenting
the implementation decisions and extensions made in HP C/HP-UX. It
is not the intent of this document to replicate the standard. Thus,
you are encouraged to refer to the standard for any fine points of
the language not covered here.
