_SVID_SOURCEDESCRIPTION
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 {
\n
char *pw_name; /* username */
\n
char *pw_passwd; /* user password */
\n
uid_t pw_uid; /* user ID */
\n
gid_t pw_gid; /* group ID */
\n
char *pw_gecos; /* real name */
\n
char *pw_dir; /* home directory */
\n
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.
