Nice. Thanks. I didn't realize you can slice a bare pointer like that.
Does druntime have any way of making sure that is safe, or are you on
your own?
No, druntime cannot know what the pointer actually points at. This would
not work in @safe code.

Also, you don't need to cast pointers to void *. Should be able

Depends on what GByte is. If it doesn't contain pointers (I'm
assuming its probably ubyte?), then it won't be scanned.

Yes, GByte is an alias for ubyte.

Hi.
I want to call a C library function that returns a data buffer as
a void*. How do I convert the resulting void* into something I
can process in D?
//I have the following function from the GDAL C library.
extern(C) CPLErr GDALReadBlock( GDALRasterBandH, int, int, void*
);
So I have (GB
