16.2.1: Convert Address

The Shm_Convert_address is responsible for converting an address of an entity in the shared memory area into the address that should be used from this node. Most targets will simply return the address passed to this routine. However, some target boards will have a special window onto the shared memory. For example, some VMEbus boards have special address windows to access addresses that are normally reserved in the CPU's address space.

void *Shm_Convert_address( void *address )
{
   return the local address version of this bus address
}
