This is not really wget problem. With using of execv() this looks to me like
you're writing your program on some Unix. If so, you should understand the
principle of the Unix exec family functions. Consult your manpage of execv,
there are more ways to do this:
1) system() - calls the program using shell and waits for its
termination
2) fork(), exec..() - forks your program into two processes
concurrently running - you can run your wget on background
3) fork(), exec..(), wait..() - this is what system() actually does
inside
There's much more on unix than just "let's run some process". Learn about all
you can do, it's awesome. :-) When you successfully run execv("wget") inside
some program without previous fork(), than your running program is instantly
on the way to meet his maker, because its running image is REPLACED by wget's.
