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



NAME
       fgetpwent - get password file entry

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

       struct passwd *fgetpwent(FILE *stream);

DESCRIPTION
       The  fgetpwent()  function  returns a pointer to a structure containing
       the broken out fields of a line in the file stream.  The first time  it
       is called it returns the first entry; thereafter, it returns successive
       entries.  The file stream must have the same format as /etc/passwd.

       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 fgetpwent() 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/passwd
              password database file
