Passing Data from a C application to a Blitz3D app

Hi all,

Does anyone have any recommendation as to how to pass data quickly from a C application (which I will write) to a Blitz app?

For the reasons of needing to use callback functions, using CallDLL is not currently an option (unless someone knows otherwise, I would love to learn how to do that)

The data will be time critical and real-time, so I need the fastest (lowest latency) possible way of channeling the data. Fortunately the data is not big - probably 2k-4k in size. But this data will need to stream to the Blitz3D app at 30-60 fps. This gives a max throughput of 240kbytes/s

much thanks in advance for any help and advice.

check out the commands copyfile and deletefile. with this commands you can write a function which should do it!
hope i understood what you meant :)

Hi DC,

Thanks for the recommendation - I have already considered using the file system - but was hoping for a method that did not involve writing and deleting files

well, i dont know but maybee it is a good idea to try byte-per-byte copyying.
you opening the a new file and copy byte per byte from the file into the other file. this can be another solution

C++ isn't one of my stronger points, however here is how banks are built up:

And here is how to use a Blitz pointer in a C++ DLL:

So, make a bank and pass "bank + 4" as a parameter to the DLL. Inside the dll, you should be able to do something like:

buffer = (unsigned int)*((int*)(buffer));
