yuzh is right ... you can add a user by invoking useradd from system() in your program ... there is no separate system call or API (atleast one that I would have heard of )

Question
How to add a new user
How do i add a new user programtically (i.e. through a function call) on unix? (and not through a shell command).
I probably just need the function name, no need to post an example unless you have one really handy.

Answers
Sunnycoder is right, there's no API. From man useradd on a Linux box
FILES
/etc/passwd - user account information
/etc/shadow - secure user account information
/etc/group - group information
/etc/default/useradd - default information
/etc/skel - directory containing default files
SEE ALSO
chfn(1), chsh(1), crypt(3), groupadd(8), groupdel(8),
groupmod(8), passwd(1), userdel(8), usermod(8)
As you can see, no APIs referenced other than crypt.
More specifically:
int function(char *username, char *password ) {
char buffer[1024];
// /usr/sbin/useradd may be specific to your system.... use $whereis useradd
snprintf(buffer, 1023, "/usr/sbin/useradd -p %s %s", password, username);
system(buffer);
return 0;
}
(this is what other people have said -- reward them with credit if this helps).

You can use system() to call "useradd" to do the job.
