Update.
2000-06-04 Kaz Kylheku <kaz@ashi.footprints.net>
Lock for stdio stream list becomes global, for use in LinuxThreads.
* libio/genops.c (_IO_iter_begin, _IO_iter_end,
_IO_iter_next, _IO_iter_file, _IO_list_lock, _IO_list_unlock,
_IO_list_resetlock): New interface for iterating global list of
streams without accessing the _IO_list_all global variable,
and for manipulating the lock which protects this list.
* libio/libioP.h: Likewise.
* libio/Version: Add entries for the new functions.
* libio/libioP.h (_IO_ITER): New typedef, just an alias for
pointer to _IO_FILE.
