After checking for NERR_* return codes, mask the return codes with 0x00FF. For example, the following sample code demonstrates how to work around this problem:

         err = NetBiosSubmit(handle, opt, ncbptr);

         if ( err == NERR_Success )
         {
             "no error"
         }
         else if ( err > NERR_BASE && err <= NERR_MAX )
         {
             "lanman error"
         }
         else if ( (err & 0x00FF) == ncbptr->ncb_retcode )
         {
             "ASSUME NetBios error"
         }
         else
         {
             "sys error or bogus return"

              switch (err)
              {
                 case    "documented OS2 errors"
                         ...

                 default "assume bogus or undocumented ret codes"
              }
         }
