[vtkusers] Altenatives to popen() in VTK

[Otahal, Thomas]

Hi all,

We are currently using the popen() function to start an external MPI job from a VTK filter. The code works fine on MAC and Linux, however for Windows we need to perform some extra quoting around the mpiexec command and its arguments to get things working properly.   Does anyone know of good alternatives to popen() that are portable across different platforms?  Ideally it would be something in VTK that gives you a platform neutral interface for starting an external process from a VTK filter.

Thanks,

--Tom
