From 766f9ed028c757561b99e4ed5aa487d381fe80a3 Mon Sep 17 00:00:00 2001 From: Pietro Gagliardi Date: Sun, 26 Aug 2018 10:19:10 -0400 Subject: Migrated util.go and main.go to the new pkgui convention and C file. Also replaced C.CBytes() with C.malloc() (this bumps our minimum version requirement to 1.8, but it's better than keeping a massive slice around at all times). --- BBB_GOFILES/util.go | 45 --------------------------------------------- 1 file changed, 45 deletions(-) delete mode 100644 BBB_GOFILES/util.go (limited to 'BBB_GOFILES/util.go') diff --git a/BBB_GOFILES/util.go b/BBB_GOFILES/util.go deleted file mode 100644 index bcd4d33..0000000 --- a/BBB_GOFILES/util.go +++ /dev/null @@ -1,45 +0,0 @@ -// 12 december 2015 - -package ui - -import ( - "unsafe" -) - -// #include -// #include "util.h" -import "C" - -// We want Go itself to complain when we're out of memory. -// The allocators in cgo *should* do this, but there isn't a -// C.CMalloc().
