You can limit the maximal number of iterations to 1 before each call
to lpx_simplex, i.e.

loop: lpx_set_int_parm(lp, LPX_K_ITLIM, 1);
      ret = lpx_simplex(lp);
      . . .
      goto loop;

In this case lpx_simplex will perform one iteration and then return.
Current basic solution components can be obtained in a usual way.
Note that the lp presolver must be disabled.

For more details see the reference manual.

Probably, yes.
