There is no such thing as 'uuidgen' in standard C++, the subject
of this newsgroup. Perhaps you will find more information on this
if you visited comp.os.linux.development.apps (or something like
that) if you expect the newsgroup to know what 'uuidgen' is.

In general, if you have a function that returns a string (like, say,
std::strcat, for example), then you can call it with appropriate
arguments and get the string back and store it for later use. Since
'uuidgen' is not a standard function, nothing can be said about it.

You want get the string printed to the shell produced by uuidgen? I'm
not experienced with this situation but i can give you an ideia, try to
pipe out the output of the file to input. Something like

system("uuidgen 1>&2"); and then call cin >> some_string; to get the

input
