Issuing system commands in Linux from C, C++

Question

I know that in a DOS/Windows application, you can issue system commands from code using lines like:

system(\"pause\");

or

s         


        

Answer 1

Not surprisingly, the command is still

system("whatever");

and the header is still stdlib.h. That header file's name means "standard library", which means it's on every standard platform that supports C.

And yes, calling system() is often a bad idea. There are usually more programmatic ways of doing things.

If you want to see how lsmod works, you can always look-up its source code and see what the major system calls are that it makes. Then use those calls yourself.

A quick Google search turns up this link, which indicates that lsmod is reading the contents of /proc/modules.
