You don't need to free your memory at all, assuming that your code needs it 
for as long as the IOC is running.  We don't have a mechanism in the IOC to 
delete records at run-time, so your asub record lifetime is the same as the 
IOC's lifetime.  The memory you allocated will get cleaned up automatically by 
the operating system when the IOC process exits on a workstation OS, or by 
vxWorks when the processor reboots.
