Subject: [PATCH 3/3] mingw: document the experimental standard handle redirection
Date: Mon, 30 Oct 2017 18:10:30 +0100 (CET) [thread overview]
Message-ID: <436f0fb010709fe0d90460dc7bc1b3482237b192.1509382976.git.johannes.schindelin@gmx.de> (raw)
In-Reply-To: <cover.1509382976.git.johannes.schindelin@gmx.de>
This feature is still highly experimental and has not even been
contributed to the Git mailing list yet: the feature still needs to be
battle-tested more.

+ (EXPERIMENTAL) Windows-only: allow redirecting the standard
+ input/output/error handles. This is particularly useful in
+ multi-threaded applications where the canonical way to pass
+ standard handles via `CreateProcess()` is not an option because
+ it would require the handles to be marked inheritable (and
+ consequently *every* spawned process would inherit them, possibly
+ blocking regular Git operations). The primary intended use case
+ is to use named pipes for communication.
++
+Two special values are supported: `off` will simply close the
+corresponding standard handle, and if `GIT_REDIRECT_STDERR` is
+`2>&1`, standard error will be redirected to the same handle as
+standard output.
