From b4d2c97a2d2cce92fa638ff74bef7dedf593fd1f Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Sat, 23 Jan 2010 22:57:23 +0800 Subject: egl: Move surface functions in egldisplay.[ch] to eglsurface.[ch] Move functions to where they should be. There should be no real change here. --- src/egl/main/egldisplay.c | 64 ------------------------------------------- src/egl/main/egldisplay.h | 55 ------------------------------------- src/egl/main/eglsurface.c | 70 +++++++++++++++++++++++++++++++++++++++++++++++ src/egl/main/eglsurface.h | 63 ++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 133 insertions(+), 119 deletions(-) diff --git a/src/egl/main/egldisplay.c b/src/egl/main/egldisplay.c index e14d0c1b63..79efa8477e 100644 --- a/src/egl/main/egldisplay.c +++ b/src/egl/main/egldisplay.c @@ -182,49 +182,6 @@ _eglCleanupDisplay(_EGLDisplay *disp) } -/** - * Link a surface to a display and return the handle of the link. - * The handle can be passed to client directly. - */ -EGLSurface -_eglLinkSurface(_EGLSurface *surf, _EGLDisplay *dpy) -{ - surf->Display = dpy; - surf->Next = dpy->SurfaceList; - dpy->SurfaceList = surf; - return (EGLSurface) surf; -} - - -/** - * Unlink a linked surface from its display. - * Accessing an unlinked surface should generate EGL_BAD_SURFACE error. - */ -void -_eglUnlinkSurface(_EGLSurface *surf) -{ - _EGLSurface *prev; - - prev = surf->Display->SurfaceList; - if (prev != surf) { - while (prev) { - if (prev->Next == surf) - break; - prev = prev->Next; - } - assert(prev); - prev->Next = surf->Next; - } - else { - prev = NULL; - surf->Display->SurfaceList = surf->Next; - } - - surf->Next = NULL; - surf->Display = NULL; -} - - #ifndef _EGL_SKIP_HANDLE_CHECK @@ -248,25 +205,4 @@ _eglCheckDisplayHandle(EGLDisplay dpy) } -/** - * Return EGL_TRUE if the given handle is a valid handle to a surface. - */ -EGLBoolean -_eglCheckSurfaceHandle(EGLSurface surf, _EGLDisplay *dpy) -{ - _EGLSurface *cur = NULL; - - if (dpy) - cur = dpy->SurfaceList; - while (cur) { - if (cur == (_EGLSurface *) surf) { - assert(cur->Display == dpy); - break; - } - cur = cur->Next; - } - return (cur != NULL); -} - - #endif /* !_EGL_SKIP_HANDLE_CHECK */ diff --git a/src/egl/main/egldisplay.h b/src/egl/main/egldisplay.h index 4b9010e76d..77458cb38d 100644 --- a/src/egl/main/egldisplay.h +++ b/src/egl/main/egldisplay.h @@ -3,7 +3,6 @@ #include "egltypedefs.h" #include "egldefines.h" -#include "eglsurface.h" /** @@ -80,14 +79,6 @@ PUBLIC void _eglCleanupDisplay(_EGLDisplay *disp); -extern EGLSurface -_eglLinkSurface(_EGLSurface *surf, _EGLDisplay *dpy); - - -extern void -_eglUnlinkSurface(_EGLSurface *surf); - - #ifndef _EGL_SKIP_HANDLE_CHECK @@ -95,10 +86,6 @@ extern EGLBoolean _eglCheckDisplayHandle(EGLDisplay dpy); -extern EGLBoolean -_eglCheckSurfaceHandle(EGLSurface surf, _EGLDisplay *dpy); - - #else /* !_EGL_SKIP_HANDLE_CHECK */ /* Only do a quick check.
