void printfoo(const char *, ...);

void
printfoo(const char *fmt, ...)
{
        va_list va;

        va_start(va, fmt);
        if (vprintf(fmt, va) < 0)
                abort();
        va_end(va);
}

int
main(int argc, char *argv[])
{
        printfoo("'%s' called with %d args\n", argv[0], argc);
