From b31255fbfdb2d9201e8d02e379b8384ee67fcfd0 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Fri, 5 Feb 2010 11:34:53 +0800 Subject: egl: Clarify IsLinked and IsBound. Both a link and a binding creates a reference to the resource. Drivers should not destroy the resource when there is a reference. The difference is better described in doc/egl.html. --- src/egl/main/eglsurface.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'src/egl/main/eglsurface.h') diff --git a/src/egl/main/eglsurface.h b/src/egl/main/eglsurface.h index feba30d4f8..0a00035730 100644 --- a/src/egl/main/eglsurface.h +++ b/src/egl/main/eglsurface.h @@ -107,6 +107,9 @@ _eglCreatePbufferFromClientBuffer(_EGLDriver *drv, _EGLDisplay *dpy, /** * Return true if there is a context bound to the surface. + * + * The binding is considered a reference to the surface.
