sprintf_s in unix?

Hi all
I have a very large program I want to run in my unix computer (Mac) and Windows at the same time.
so I have defined:

Code:

#ifndef WIN32
void sprintf_s(char *buffer, size_t sizeOfBuffer, const char *format, ...) {
	sprintf(buffer, format, ...); //ERROR: expected primary-expression before '...' token
}
#endif

How can I solve this error?

I use to have

Code:

#define	sprintf_s(buffer, buffer_size, stringbuffer, number) (sprintf(buffer, stringbuffer, number))

but it does not work with any number of arguments as the real sprintf_s

Help is appreciated, thanks

Ignacio

sprintf_s is not part of the standard C library so is not portable.

However, snprintf is, and you should be able to accomplish what you want with that. It's nearly identical, I think.

Thanks MK27, I completely forgot about snprintf().

AFAIK, it does not work correctly in MSVC. The return value etc.

GCC supports vararg macros.

Code:

#define	sprintf_s(buffer, buffer_size, stringbuffer, ...) (sprintf(buffer, stringbuffer, __VA_ARGS__))

Not 100% sure about the syntax.

BTW, VC++2005+ does too.
