From 18e43565574b700befc832ed4d25d25e40951f68 Mon Sep 17 00:00:00 2001 From: Laurent Bercot Date: Tue, 24 Nov 2020 21:45:56 +0000 Subject: Complete revamp of the pathexec functions - pathexec_run is now called exec_ae a for provided file name (default: argv[0]) e for provided envp (default: environ) - pathexec is now called mexec. m for merge environment. Option letters are: a for provided file name (default: argv[0]) e for provided envp (default: environ) f for provided envp *and* length of the envp m for provided modif string plus its length (the length is always needed because the modifs are null-terminated) n for provided modif string, length *and* number of modifs - functions have a foo0 version for _exit(0) when argv[0] is null - functions have a xfoo version to die if the exec fails - and a xfoo0 - Compatibility #defines and #includes are there until the next major bump --- NEWS | 1 + doc/upgrade.html | 1 + package/deps.mak | 69
