NAME    [Toc]    [Back]

       getpwent, setpwent, endpwent - get password file entry

SYNOPSIS    [Toc]    [Back]

       #include <pwd.h>
       #include <sys/types.h>

       struct passwd *getpwent(void);

       void setpwent(void);

       void endpwent(void);

DESCRIPTION    [Toc]    [Back]

       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 <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 */
	      };

RETURN VALUE    [Toc]    [Back]

       The  getpwent() function returns the passwd structure, or NULL if there
       are no more entries or an error occurs.
