I want to create user in linux. I want to know how to create multiple uers using c++ in linux os .

foo_bar_foo · 11-28-2004, 10:25 PM

mostly people just use scripting for this but the useradd program is in the shadow
package and that would be the place to look i guess

phoenix_fei · 11-28-2004, 11:26 PM

can you give me a in details .

itsjustme · 11-28-2004, 11:48 PM

$ useradd -m username

Also, I've never heard of a distribution named 'worket', but the useradd command should work. maybe...

thanks, itsjustme
but i want to user C++ to achieve it.
can you help me?
please give some advice .

Oh... Sorry.. I didn't see the C++ part. (it's late and I should be in bed.

)
Can't help you there.

You can run shell commands using the exec family of functions so you can create a user using the exec commands in C. Declared in unistd.h

See the linux programmers' manual pages for the exec family of functions and you should get help for it. Note that to create users, you need to have root access.

Here's a C++ sample code:

Code:

system("useradd -m username");

@jlliagre: Does the system command do the same thing as the execve command?

jlliagre · 11-29-2004, 01:49 AM

Yes, it's an higher level and simpler function, using the fork and exec system calls under the cover.

Just to depart slightly, in future, please use a more useful thread title. "Please, Come Here" tells us nothing at all about your problem and many members just skip over threads like yours. All threads get at least looked at, so your title is redundant.

Thanks

For a more complete example of a program to add users take a look at my post on the following thread: http://www.linuxquestions.org/questi...readid=259442.

I used C along with the system() library function to execute the command useradd. I also had to use the crypt() function to set a password otherwise the account is setup disabled.
