Subject: [PATCH] Fix __fp_lock_all() and __fp_unlock_all()
Date: Wed, 18 May 2022 19:13:05 +0200	[thread overview]
Message-ID: <> (raw)

For _REENT_GLOBAL_STDIO_STREAMS, lock/unlock all FILE objects.  In the
repository, this function is only used by Cygwin during process forks.  Since
Cygwin enabled _REENT_GLOBAL_STDIO_STREAMS recently, without this fix no FILE
object at all was locked.
