system() or _popen()?

[Michael]

Hello,

I am currently writing a C++ app to ftp new files.
The C++ program will ftp to a server, get a list of files,
compate that to a list of files already received and ftp
the new files.

Was using DOS script with various calls to small C++ programs
but got very bulky and complex. Now, I am trying to write
one C++ program to do all of the work.

My question is can I use either system() or _popen to
call "ftp" and capture the return code? Also, if someone
has done something similar, it is easier to pipe the ftp
output to a file and look at it, or could I just read through
the buffer output?

Thanks much!

If you want a portable C++ program, system() is the only thing
available. Otherwise, you are in the wrong group.

How would you read through the output with system()?

Redirect the output of the controlled system, using the system's
facilities for that (e.g. > on most ommand lines) then read back
the created file, using ifstream.
