I am trying to write a front end to the MicroSoft 5.X sscanf function
to allow users to use a default value.  The problem I am having is that
I can't pass the parameters from the called function to sscanf.

Does anyone help here?  Perhaps I need a 'vsscanf' function?

Example:

#include <stdio.h>

main ()
{
	double u = 1.0, v = -1.0;

	Myscanf ("Enter u", "%lf", &v);

	Myscanf ("Enter u, v", "%lf %lf", &u, &v);
}

Myscanf (const char *p, const char *f, ...)
{
	char b [80];

	printf ("%s: ", p);

	gets (&b);

	if (strlen (b) != 0) sscanf (f, ????);
}

Jon
