Subject: [PATCH] Fix __fp_lock_all() and __fp_unlock_all()
Date: Wed, 18 May 2022 19:13:05 +0200 [thread overview]
Message-ID: <20220518171307.53663-1-sebastian.huber@embedded-brains.de> (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.
