示例1: eglGetCurrentSurface
EGLAPI EGLSurface EGLAPIENTRY eglGetCurrentSurface(EGLint readdraw) {
if (!EglValidate::surfaceTarget(readdraw)) {
return EGL_NO_SURFACE;
}
ThreadInfo* thread = getThreadInfo();
EglDisplay* dpy = static_cast<EglDisplay*>(thread->eglDisplay);
ContextPtr ctx = thread->eglContext;
if(dpy && ctx.Ptr()) {
SurfacePtr surface = readdraw == EGL_READ ? ctx->read() : ctx->draw();
if(surface.Ptr())
{
// This double check is required because a surface might still be
// current after it is destroyed - in which case its handle should
// be invalid, that is EGL_NO_SURFACE should be returned even
// though the surface is current.
EGLSurface s = (EGLSurface)SafePointerFromUInt(surface->getHndl());
surface = dpy->getSurface(s);
if(surface.Ptr())
{
return s;
}
}
}
return EGL_NO_SURFACE;
