<h3>GETPWENT(3)         Linux Programmer's Manual         GETPWENT(3)
</h3>

<h3>NAME
</h3>       getpwent, setpwent, endpwent - get password file entry

<h3>SYNOPSIS
</h3>       #include &lt;pwd.h&gt;
       #include &lt;sys/types.h&gt;

       struct passwd *getpwent(void);

       void setpwent(void);

       void endpwent(void);

<h3>DESCRIPTION
</h3>       The  getpwent()  function returns a pointer to a structure
       containing  the  broken  out  fields  of   a   line   from
       /etc/passwd.   The  first time it is called it returns the
       first entry; thereafter, it returns successive entries.

       The setpwent() function rewinds the file  pointer  to  the
       beginning of the /etc/passwd file.

       The endpwent() function closes the /etc/passwd file.

       The passwd structure is defined in &lt;pwd.h&gt; 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 */
              };

<h3>RETURN VALUE
</h3>       The  getpwent()  function returns the passwd structure, or
       NULL if there are no more entries or an error occurs.

<h3>ERRORS
</h3>       ENOMEM Insufficient memory to allocate passwd structure.

<h3>FILES
</h3>       /etc/passwdpassword database file

<h3>CONFORMING TO
</h3>       SVID 3, BSD 4.3
