System function, output to file
Please support our C++ advertiser: Programming Forums - DaniWeb Sister Site
Thread Solved |
(c++)
Ok so I understand how to use the system function, and how to output to a file. How do I pipe the output of say system("last") to a file?
system() returns an int, so if I mystream << system("last") it will put an int in the file. I need to intercept the output going to the screen(cout?) and put it in the file (mystream? or can I do this in the last command with some parameters?)
Thanks

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
Thanks that got it. I didn't know that one but I do now. Appreciate the help.
