In the simplest case, you would define a function spec:
function system (cmd : in string) return integer;
and implement it by pragma import (C, system).
Pass the command to be executed in the cmd parameter, adding an "&" if you
don't want to block, (and an ASCII nul always).
To be more correct, use the appropriate types out of interfaces.C(.*) for
int and string. That helps in converting Ada strings to C char arrays.
Check your system to see which shell the system call executes the command
under -- this can make a difference!
