How about making the entry into the password file directly. fopen(3S) it
directly and append your entry to it as it is a simple text file.
The password you have entered from the user (unencrypted) can be encrypted
using the crypt(3C) library function.
If you do this you can also think about using
alternative methods for generating the salt. gettimeofday(3C) is
traditional but you can also use alternatives like gethrtime(3C).
Invoking useradd and the likes may not be such a good idea. when you can
do the above. It is much simpler too !
