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);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       fgetpwent(): _SVID_SOURCE

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 referred to by stream must have the
       same format as /etc/passwd (see passwd(5)).

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

           struct passwd {
               char   *pw_name;       /* username */
               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 a pointer to a passwd structure, or NULL if there are  no
       more  entries  or an error occurs.  In the event of an error, errno is set to indicate the
       cause.

ERRORS
       ENOMEM Insufficient memory to allocate passwd structure.

FILES
       /etc/passwd
              password database file

CONFORMING TO
