Re: how to pass a malloc'd C string over to be managed by the GC

[Kagamin via Digitalmars-d-learn]

byte[] snappyCompress(in byte[] plaintext) {
        import deimos.snappy.snappy;
	size_t output_length = 
snappy_max_compressed_length(plaintext.length);
        byte[] output = new byte[output_length];
	if(snappy_compress(cast(char*)plaintext.ptr, plaintext.length, 
cast(char*)output.ptr, &output_length) == SNAPPY_OK) {
                byte[] compressed = output[0..output_length];
                // <---- do something magical here
                return compressed;
        }
        assert(0);
}
Snappy works on bytes, not text, char is a wrong type there.
