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
