Hi,
here is a minimal example. How should I properly release
the surface and anything that is attached to it?
1.) valgrind shows use after free in the windowstack
2.) IDirectFBSurface->Clear() creates a memory leak, this is with
directfb-1.4 as of today.
#include <directfb.h>
int main(int argc, char **argv)
{
DFBResult ret;
IDirectFB *dfb;
IDirectFBSurface *surface;
/* Initialize DirectFB. */
ret = DirectFBInit( &argc, &argv );
if (ret) {
D_DERROR( ret, "DFBTest/Resize: DirectFBInit() failed!\n" );
return ret;
}
/* Create super interface. */
ret = DirectFBCreate( &dfb );
if (ret) {
D_DERROR( ret, "DFBTest/Resize: DirectFBCreate() failed!\n" );
return ret;
}
DFBSurfaceDescription surfaceDesc;
memset(&surfaceDesc,0,sizeof(DFBSurfaceDescription));
surfaceDesc.width = 100;
surfaceDesc.height = 200;
surfaceDesc.caps = DSCAPS_PREMULTIPLIED;
surfaceDesc.pixelformat = DSPF_ARGB;
surfaceDesc.flags = DFBSurfaceDescriptionFlags(DSDESC_WIDTH |
DSDESC_HEIGHT | DSDESC_CAPS | DSDESC_PIXELFORMAT);
for (int i = 0; i < 10; ++i) {
dfb->CreateSurface(dfb , &surfaceDesc, &surface);
surface->Clear(surface, 0, 0, 0, 0);
surface->Release(surface);
}
dfb->Release(dfb);
return 0;
}
