wxWidgets/include/wx/process.h
Guilhem Lavaux 8b33ae2d5a Inserted "stdio catch" in wxExecute. The activation is controlled by wxProcess.
Completed some TODO in wxMMedia (wxSoundUlaw, ...)
Reworked the PCM converted: it should be simpler to add converters now and it is
cleaner.
Implemented status information in wxVideoWindows but it doesn't work on my
Win98SE (UNSUPPORTED_FUNCTION)
Changed *ERR into *ERROR
Added a TODO: we must detect the best format in wxSoundWindows
