Andreas,

Thanks for code, but should this not be in the image, associated in some way with ExternalAddress and/or ByteArray?

Can I simply use a ByteArray to make a buffer that I pass to an external library?  My understanding is that it could be moved by the gc (ouch!!)  Am I wrong?  If there is a way to instantiate a byte array that won't move, great.  What about ExternalAddress>>finalize?

Bill

You mean like:

memcpyTo: destAddr from: srcAddr length: sz
	<cdecl: long 'memcpy' (void* void* ulong) module: 'libc.so'>
	^self externalCallFailed
