From 2a973ab7f1a6f6cd9be1c7257fd7b5d331515eab Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Wed, 12 Sep 2018 10:30:46 -0300 Subject: posix: Add internal symbols for posix_spawn interface This patch adds internal hidden definition for mostly of the posix_spawn function so it can be used internally on both popen and system implementations.
