I know there’s much more elegant ways of sending encoded data to and from an IMP/Agent, but I’m stuck with having to send and receive a binary proprietary protocol (just a struct byte stuffed in an array) between the host uP and the IMP. In straith C (on the uP), retrieving the struct elements out of the byte array is as easy as type casting the struct on to the array (given no problems with endianness etc :-), but what would be an elegant way of retrieving the various elements of the struct out of the received byte array in squirrel ? (if no better ideas, I can always go back to the old tedious and error prone byte mapping into various variables, but that’s as ugly as can be 
I’m afraid there’s no equivalent of struct mapping; the best you can do is to put the data in a blob and treat it as a stream, using blob.readn() to extract different types as if it were a file.
