digitalmars.D - Setting a dynamic array from a pointer to data...

Hi all,

I have a unsigned char* buffer from an external library that I know is 
sized, for example, 100.

What is the best way to turn it in a ubyte[] dynamic array?

Thanks

ubyte *buffer = whatever();

ubyte[] dynBuffer = buffer[0..100];

Nope.  It just sets the dynamic array's pointer to that data.
