From a653a495d8e467ab776b850c481657776e004794 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?IOhannes=20m=20zm=C3=B6lnig?= Date: Fri, 20 Jan 2006 10:28:50 +0000 Subject: split z_sigbin.c into separate files and adapted to the hexnameloader of the upcoming pd-0.40; changed the "dot.c" into "0x2e.c" (conforms to the hexnameloader) so now each object is in a separate c-file which reflects the object's name in a generic way svn path=/trunk/externals/zexy/; revision=4452 --- src/0x3e0x7e.c | 260 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 260 insertions(+) create mode 100644 src/0x3e0x7e.c (limited to 'src/0x3e0x7e.c') diff --git a/src/0x3e0x7e.c b/src/0x3e0x7e.c new file mode 100644 index 0000000..081620a --- /dev/null +++ b/src/0x3e0x7e.c @@ -0,0 +1,260 @@ +/****************************************************** + * + * zexy - implementation file + * + * copyleft (c) IOhannes m zmölnig + * + * 1999:forum::für::umläute:2004 + * + * institute of electronic music and acoustics (iem) + * + ****************************************************** + * + * license: GNU General Public License v.2 + * + ******************************************************/ + +/* + finally :: some of the missing binops for signals :: >~ + + 1302:forum::für::umläute:2000 +*/ + +#include "zexy.h" + +/* ------------------------ relational~ ----------------------------- */ + +/* ----------------------------- gt_tilde ----------------------------- */ +static t_class *gt_tilde_class, *scalargt_tilde_class;
