Hello Luigi,

From your description, you seem to be looking for LocalProcess, and its global functions:

https://www.ultimatepp.org/src$Core$AProcess$en-us.html (See the end of the doc. Sys() command may be what you are looking for.)
And
You may want to use it with https://msdn.microsoft.com/en-us/library/windows/desktop/aa3 65530(v=vs.85).aspx on windows.
Best regards,
