diff command?

[Lionel van den Berg]

Hi all,

I'm wondering if there is a diff function like the unix command in C++?

In fact I would like to know if you can call the unix (I should say
*nix) command from within a c++ application?

Also I have a binary that has been compiled by a friend, is there a way
to call it from within a C++ application and pass it a parameter?

thanks,

Lionel.

No.

Use 'system' function. RTFM.

Also I have a binary that has been compiled by a friend, is there a way to
call it from within a C++ application and pass it a parameter?

Yes, use 'system' function. Also, search the newsgroup archives for the
keywords "system function C++". You will see more recommendations, I am
sure.

#include <stdlib.h>

int main ()
{
int retval = system ("diff foo bar");
}

'popen' is not a standard C or C++ function. When giving an off-topic
response it is customary to supply some kind of explanation. Thanks.

It's a posix standard.
