Hello,

By any chance does anyone know how to perform a system call (something that would be done at command line, such as "useradd" or "passwd") on a UNIX OS (RHLinux7.2, to be specific) in C or C++?

Thanks!

system();

Try man system for more info.

wow. I feel stupid. Thanks! (new to c/c++ - I'd 100% use Java if it wasnt so much slower)

Uhm, those two aren't syscalls. System calls are things like fcntl() or ioctl().

What you need is popen(3), system(3), exec(3), etc.
Refer to the documentation :)
