How do to SCP from within my C++ program?

Maybe. But both Unix and Windows return the exit code of the
child process, and in both cases, 0 means success (and in both
cases, there are programs which return random exit codes).

The real portability problem is what to put in the string you
pass to system. "ls -lt" will have decidedly different results
on a Unix machine than under Windows (unless you've installed
CygWin and have it in your path). And more complicated commands
may work differently on different flavors of Unix, even without
taking Windows into consideration. Or they may work differently
depending which packages you have installed under Linux, even
without taking different flavors of Windows into consideration.

One downside of system() the caller doesn't know if the command

succeeded or failed.

Call a script that save the return value? Using system() is the simplest
and immediate solution, until you find a free SCP library....

But I am posting from comp.lang.c++ and fork() doesn't exist ;-)

What do you mean by fork() does not exist?

The very first line in the original posting stated --

"I'm writing C++ code that is running on a *Solaris* system."

The real portability problem is what to put in the string you

pass to system.

If portability is a concern sftp should be used in preference to scp.
