Your description is not entirely clear. When is the buffer allocated,
and when does it need to be freed?
Note that not only can you not use locks/mutexes etc, you should not
call any memory allocation functions (new/delete, malloc()/free() etc)
in your RemoteIO callback.
If you have a producer/consumer situation where the buffer is generated
in a non-real-time thread and then played by the RemoteIO thread, you
can set up a couple of lock-free queues and pass the buffer pointer back
and forth between NRT and RT thusly:
in NRT:
allocate buffer
generate buffer
pass to RT via queue A
in RT:
use buffer in RT
pass buffer to NRT queue B
in NRT:
free buffer
Hope that helps.
Ross.
