Subject: [PATCH v2 3/3] mingw: document the standard handle redirection
Date: Wed, 1 Nov 2017 18:10:33 +0100 (CET) [thread overview]
Message-ID: <80b58f364375a72d7efd547a90f284accfeab877.1509556153.git.johannes.schindelin@gmx.de> (raw)
In-Reply-To: <cover.1509556153.git.johannes.schindelin@gmx.de>
This feature has been in Git for Windows since v2.11.0(2), as an
experimental option. Now it is considered mature, and it is high time to
document it properly.

+ Windows-only: allow redirecting the standard input/output/error
+ handles to paths specified by the environment variables. 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
+ (e.g. `\\.\pipe\my-git-stdin-123`).
++
+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.
