Comment(by axeld):
Cursors don't use just ServerBitmaps, but its own subclass, so I'm afraid
one doesn't get around doing that, at least I don't think adding the
CursorBitmaps to an application would work out that good (for those
bitmaps, there is always one ServerApp that actually owns the bitmap). I
guess it could made work, but it should be way easier to go the seemingly
silly road of sending the data to the client, and let it create the
BBitmap itself.
Since the link is read one date after the other, you could have code like
this (might be pseudo code, it's been a while since I looked at that API):
{{{
uint32 size = link.Read<uint32>();
void* data = malloc(size);
if (data == NULL)
return B_NO_MEMORY;
link.Read(data, size);
// ...
// read other bitmap values, and create bitmap
bitmap->SetBits(data, ...);
}}}
