* Could we use <code>spawn</code> with <code>P_WAIT</code> instead? IIUC, that would require passing the return code from the spawned process.

** '''[jwe]''' We have too many different ways of starting and interacting with subprocesses (popen, popen2, system, spawn, procbuf, procstream, etc.). Is it possible to use just one C++ function to provide all the public functions we need to support? | ** '''[jwe]''' We have too many different ways of starting and interacting with subprocesses (popen, popen2, system, spawn, procbuf, procstream, etc.).

*** '''[mmuetzel]''' Afaict, there is currently no standard C++ function that would do that. Maybe <code>std::process</code> could fill that gap once/if it makes it into the standard (maybe C++23?): [http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1750r1.pdf P1750R1 A Proposal to Add Process Management to the C++ Standard Library] | |||
** '''Long term:''' Get rid of the wrapper program on all platforms. That would require the new command line interface and the possibility to dynamically load the GUI (optionally). This will probably not happen before Octave 8. | ** '''Long term:''' Get rid of the wrapper program on all platforms.
