Passing ellipsis to C

[Mike - EMAIL IGNORED]

Consider:

#include <syslog.h>

// Open syslog in constructor.

void
MyClass::
MyMemberFunctio n(...)
{
syslog(LOG_INFO ,???);
}

Now I assume that syslog is a C function, using C type varargs, etc.
Is this correct? I want to pass the ellipsis to syslog. Can
I do this? How? I have heard that there might be an incompatibility .

Thanks for your help.
Mike.

There is no such standard header. If you want us to consider it, you
need to explain what it contains.

// Open syslog in constructor.

void
MyClass::
MyMemberFunctio n(...)
{
syslog(LOG_INFO ,???);
}

Why do you assume that? There is no such _standard_ C function.

There is no way to pass "whatever arguments were passed to me" down to
some other function that is also declared with ellipsis. It is usually
done by calling a different function, which is made to accept 'va_list'.
See an implementation of 'printf' as an example.

Don't assume...
It is a C function that takes a format string (like printf).

Try 'man syslog' for details.
