Hello, I am working with scalar values and fixed-length arrays. I need to deserialize the entire message into a contiguous raw buffer in memory such that all members of the data structure can be accessed by using offsets against a pointer to the raw buffer. This is due to the need for certain devices to have having "DMA access" to the deserialized message contents in system memory. If I use Protocol Buffers can I make sure that the entire deserialized message (including arrays of known size) is in a contiguous buffer in memory?
I am currently using XDR (eXternal Data Representation, i.e. Sun RPC) as my wire format, which has very good support for fixed-length arrays ... I always know exactly where my data is in memory, but this comes at the expense of having to statistically specify the exact size of each message.I would like to migrate to Protocol Buffers as a wire format but I working in a somewhat lower level C environment where I need to know the system memory address of the deserialized data so that I can issue DMA commands to access it from some device.
