Wojciech Galazka made a long filename program LFN0005 for Windows NT 4
I tried to to use it from a Watcom / Causeway Dos extended program which
runs with long filesnames in Win9x, but it did not return valid
informations.
The lfnload.com and the dll report installed ok on screen
I used the following code to convert a filename from long to short:

int IntrGetNameFunctions(unsigned short subcall,char *infile, char *outfile)
{
     struct SREGS sregs;
     union REGS regs;

     segread(&sregs);
     sregs.ds=FP_SEG(infile); // vector address
     regs.x.esi=FP_OFF(infile);
     sregs.es=FP_SEG(outfile); // info dump address
     regs.x.edi=FP_OFF(outfile);
     regs.h.cl=subcall; // Get full path/long/short
     regs.h.ch=0x80; // Use Subst drive
     regs.w.ax=0x7160; // UserErrTerm
     int386x(0x21,&regs,&regs,&sregs);
     return (regs.w.cflag);
}
