From f4c20290509d7ed3a8fd5304577e7a4cc0b9d974 Mon Sep 17 00:00:00 2001 From: Mike Buland Date: Tue, 3 Apr 2007 03:49:53 +0000 Subject: Ok, no code is left in src, it's all in src/old. We'll gradually move code back into src as it's fixed and re-org'd. This includes tests, which, I may write a unit test system into libbu++ just to make my life easier. --- src/paramproc.cpp | 514 ------------------------------------------------------ 1 file changed, 514 deletions(-) delete mode 100644 src/paramproc.cpp (limited to 'src/paramproc.cpp') diff --git a/src/paramproc.cpp b/src/paramproc.cpp deleted file mode 100644 index a352e66..0000000 --- a/src/paramproc.cpp +++ /dev/null @@ -1,514 +0,0 @@ -#include "paramproc.h" -#include - -#define ptrtype( iitype, iiname ) \ - ParamProc::ParamPtr::ParamPtr( iitype *iiname ) : \ - type( vt ##iiname ) { val.iiname = iiname;
