Hi,

I was wondering about allocating memory for opcodes, should one always use the AuxAlloc function to allocate memory for opcodes? If Calloc and such are used will this possibly block the performance thread? I was wondering also about using csounds circular buffer, will that block performance when that is allocated / de-allocated?

You should always AuxAlloc because it is linked to memory management of instruments. If you use something else, memory will leak.

Is it not then advisable to use the circular buffer? I looked at it’s code and it seems to use Malloc, I was using it in my web sockets opcode to send data to another thread.

Not only there, but also when replacing instruments with dead instances.

Memory should be allocated at init time, in —realtime mode this is done at a separate thread, not interrupting the
main thread. In normal mode, it might on occasion block if there is a huge amount to be allocated. In practice it has not been a problem.
If you are creating a circular buffer, make sure you implement an opcode dealloc callback to destroy it too.
