What's the difference between the getmypid() and the posix_getpid() functions?
I turned to getmypid() because my script has to run both on Windows and on Linux.
It seems the main difference is what you said :
getmypid works both on windows and linuxposix_getpid does not work on windows, as stated hereI guess the second one exists to be kinda POSIX-compliant (if there are others POSIX functions, why not this one ? )
So, if you want your code to be portable, you'll use the first one -- as you did.
