From ccf08bc3d06050fbe9b76846f6e2ab6d1cd6bd09 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Tue, 22 Jul 2008 03:12:46 -0400 Subject: run-command: add pre-exec callback This is a function provided by the caller which is called _after_ the process is forked, but before the spawned program is executed. On platforms (like mingw) where subprocesses are forked and executed in a single call, the preexec callback is simply ignored. This will be used in the following patch to do some setup for 'less' that must happen in the forked child.
