From dd7595a3475407a7fa96a97393bae8c5220e8762 Mon Sep 17 00:00:00 2001 From: David Walter Seikel Date: Wed, 4 Jan 2012 18:41:13 +1000 Subject: Add the base Enlightenment Foundation Libraries - eina, eet, evas, ecore, embryo, and edje. Note that embryo wont be used, but I'm not sure yet if you can build edje without it. --- .../evas/src/modules/engines/buffer/evas_engine.c | 403 +++++++++++++++++++++ 1 file changed, 403 insertions(+) create mode 100644 libraries/evas/src/modules/engines/buffer/evas_engine.c (limited to 'libraries/evas/src/modules/engines/buffer/evas_engine.c') diff --git a/libraries/evas/src/modules/engines/buffer/evas_engine.c b/libraries/evas/src/modules/engines/buffer/evas_engine.c new file mode 100644 index 0000000..e8dff7a --- /dev/null +++ b/libraries/evas/src/modules/engines/buffer/evas_engine.c @@ -0,0 +1,403 @@ +#include "evas_common.h" +#include "evas_private.h" +#include "evas_engine.h" +#include "Evas_Engine_Buffer.h" + +/* domain for eina_log */ +/* the log macros are defined in evas_common.h */ +/* theirs names are EVAS_ERR, EVAS_DBG, EVAS_CRIT, EVAS_WRN and EVAS_INF */ +/* although we can use the EVAS_ERROR, etc... macros it will not work + when the -fvisibility=hidden option is passed to gcc */ + +int _evas_engine_buffer_log_dom = -1;
