DESCRIPTION
       addlotrs creates a new transistor, and adds it to the list of
       transistors pointed to by ptfig->LOTRS. The new transistor is added in
       front of the list, and becomes itself the list head.
       The type parameter can take six values :

              TRANSN              for a N channel transistor

              TRANSP              for a P channel transistor

              TRANSN_FAST         for a high speed N channel transistor

              TRANSP_FAST         for a high speed P channel transistor

              TRANSN_HVIO         for a low leakage N channel transistor

              TRANSP_HVIO         for a low leakage P channel transistor

       The x, y, width , length, ps, pd, xs and xd,  arguments fill
       respectivly the X, Y, WIDTH, LENGTH, PS, PD, XS and XD fields.
       Four connectors are created each time a transistor is added, and the
       ptgrid, ptsource, ptdrain and ptbulk losigs are attached to the SIG
       field of the locon of the appropriate connector. The connectors names
       are grid, source, drain and bulk, their direction, DIR, are set to 'T',
       and their TYPE INTERNAL.  For details on the structures, see locon(3)
       and lotrs(3).

RETURN VALUE
       addlotrs returns a pointer to the newly created transistor.

ERRORS
       "∗∗∗ mbk error ∗∗∗ illegal transistor type : type"
              The type is not a legal transistor type.

EXAMPLE
       #include "mlo.h"
       void n1_y() /∗ transistor netlist of an inverter ∗/
       {
       lofig_list ∗pt;
       losig_list ∗in, ∗out, ∗vdd, ∗vss;
          pt = addlofig("n1_y");
          addlocon(pt, "in", in = givelosig(pt, 0), IN);
          addlocon(pt, "out", out = givelosig(pt, 1), OUT);
          addlocon(pt, "vdd", vdd = givelosig(pt, 2), IN);
          addlocon(pt, "vss", vdd = givelosig(pt, 3), IN);
          addlotrs(pt, TRANSN, 0, 0, 6, 1, in, vss, out, vss, trn_n1_y);
          addlotrs(pt, TRANSP, 0, 0, 12, 1, in, vdd, out, vdd, trp_n1_y);
       }
