int putpwent(const struct passwd *p, FILE *stream); 

The putpwent() function writes a password entry from the structure p in the file associated with stream.

The passwd structure is defined in <pwd.h> as follows:

struct passwd {
        char    *pw_name;       /* user name */
        char    *pw_passwd;     /* user password */
        uid_t   pw_uid;         /* user id */
        gid_t   pw_gid;         /* group id */
        char    *pw_gecos;      /* real name */
        char    *pw_dir;        /* home directory */
        char    *pw_shell;      /* shell program */
};

The putpwent() function returns 0 on success, or -1 if an error occurs.
