inline functions and argument lists

[jamihuq]

Hello all,
I just wondering if the following is supported in C:

inline char* myfunc(unsigned int aLen, char *aFormat, ...)

Thanks
Jami

inline is only supported in C99 (though some pre-C99 compilers may
support it as an extension). Other than that, I don't see any problem
with it.

As for ... (ellipse) that refers to variable argument lists, yes that
is also supported in almost all compilers. (Haven't seen any C compiler
not supporting it).

All C compilers support it, in that any compiler that does not
support it is not a C compiler.

That feature has been in the language since the 1989 ANSI standard
(equivalent to the 1990 ISO standard). It's almost certainly no
longer necessary to worry about old compilers that don't support at
least that standard.

Unless it's a pre-ansi one. The compiler on unix v7 didn't have variadic
arguments.

At least not in their current form. Before ANSI introduced
<stdarg.h>, there was a <varargs.h> header which could be used to
implement things like printf(); some systems still support it.
(Unless Unix V7 predates printf().)

v7 did not use macros to implement printf - it used messy pointer
arithmetic directly.

Looks ok if you're using a c99 compliant compiler for the /inline/ bit.

However, you do know that on 'inline': it's just necessary for a compiler to
*not* produce a syntax error when it sees it, i.e., as long as it recognises
the keyword, it doesn't have to pay it any further attention.
