This is a function taken from "write.c" in "mfwrite.zoo" posted in cbip this
year and archived in Simtel20 (don't know exact location, it's a batch utility):


void getpath(void)
/*
 * Stores the current path into `path' and the true path into `true_path'.
 * The true path is obtaind by the dos function call 0x60.
 * DS:SI is input path; ES:DI is output path.
 */
{
        union REGS r;
        struct SREGS s;

        if (*path != '\0')   /* i.e. second call */
                return;
        getcwd (path, MAXPATH);
        r.x.ax = 0x6000;
        /* assuming near pointers: */
        r.x.si = (unsigned)path;
        r.x.di = (unsigned)true_path;
        segread(&s);
        s.es = s.ds;
        intdosx(&r,&r,&s);
}


If the string in "true_path" starts with "\\" ("\\\\" in c-notation), then
you are dealing with a (novell) network path.  If not, different strings
mean either joined or subst'ed drives.

Good luck,
