From a915459097b72da9cc058172a54029352b684b0f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ren=C3=A9=20Scharfe?= Date: Sun, 19 Oct 2014 13:14:20 +0200 Subject: [PATCH] use env_array member of struct child_process Convert users of struct child_process to using the managed env_array for specifying environment variables instead of supplying an array on the stack or bringing their own argv_array. This shortens and simplifies the code and ensures automatically that the allocated memory is freed after use.
