    GETPWENT(3)         Linux Programmer's Manual         GETPWENT(3)

    NAME
           getpwent, setpwent, endpwent - get password file entry

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

           struct passwd *getpwent(void);

           void setpwent(void);

           void endpwent(void);

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

    ERRORS
           ENOMEM Insufficient memory to allocate passwd structure.

    FILES
           /etc/passwdpassword database file
