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 a pointer to a passwd structure, or NULL if there are no more entries or an error occurs.

ERRORS

Insufficient memory to allocate passwd structure.
