/* Format of an RPC packet:
*
* All integers are encoded in big-endian style (network byte order).
* INT16s take 2 bytes; INT32s take 4.
* Byte arrays are encoded as an INT16 length followed by the data.
* Strings are encoded as a byte array including the null terminator.
*
* A packet consists of a header (generated by win32_mailslot() in drvwin32.c)
* and a body (generated by rpccli.c and parsed by rpcserv.c). Other RPC
* implementations may use a different header, or none.
*
* Structures are packed as each of their members, one after the other.
* Driver pointers are mapped to integer handles.
*
* The first INT16 of the body is the function number defined just below. The
* rest of the body varies according to what function is being performed.
* */
/* Note: Although RPC IDs are defined for all libdsk functions,
* only a small subset are currently implemented. */
