notcurses/include/ncpp/Subproc.hh
Marek Habersack e23d5baea4 [C++] Sync API changes
Added:

  * class FDPlane (`ncfdplane*`)
  * class Subproc (`ncsubproc*`)
  * NotCurses: get_inputready_fd (`notcurses_inputready_fd`)
  * Plane: qrcode (`ncplane_qrcode`)
  * class PlotBase: templated base class for Plot variations
  * class PlotU: `uint64_t` instantiation of PlotBase (aliased to previous
    `Plot` class for source compatibility), `ncuplot*`
  * class PlotD: `double` instantiation of PlotBase, `ncdplot*`
