system
normally waits for the child process to finish, but there are exceptions.
If you do
system "... &"
on unix,
system
will return without waiting for the child process to finish.
If you do
system -1, ...
on Windows,
system
will return without waiting for the child process to finish.
Some application launch another application and exit immediately (like the Windows command
start
), so
system
would return immediately too.
Running a windowed (as opposed to console) application in Windows will also cause
system
to return immediately (IIRC).
