NAME

       fgetpwent - get password file entry

LIBRARY

       Standard C library (libc, -lc)

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():
           Since glibc 2.19:
               _DEFAULT_SOURCE
           glibc 2.19 and earlier:
               _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
       error.

ERRORS

       ENOMEM Insufficient memory to allocate passwd structure.

FILES

       /etc/passwd
              password database file
