Very Computer

Gentlemen,
Im writing a program that read all user in /etc/shadow, and for each user,
him generate a ramdom number, set this number as password and then, will to
send a email (calling perl::system()) to this user with the password
generated.

Its alright, except which i need record the new password in shadow

The source follow below:

#include <unistd.h>
#include <stdio.h>
#include <shadow.h>

int main(int argc,char * argv[])
{
        char *cpw, *login, *senha;
        char buf[200];
        struct spwd *shad;

        setspent();
        shad = getspnam(argv[1]);
        login = (char *)shad->sp_namp;
        senha = (char *)shad->sp_pwdp;

        // Below im trying set the password returned by crypt function
        // to struct of shadow.( i think that here im missing)
        shad->sp_pwdp = (char *)crypt(argv[2],argv[2]);

        // The two lines below, are my debug :-)
        sprintf(buf, "Login: %s\nSenha: %s\n", login, senha);
        printf("%s",buf);

        endspent();

Im Waiting for any help!

You can't use the getsp* functions to change /etc/shadow.  Your
program will have to rewrite it manually.

Correct this....Is getsp* for changing the sp entries ?
