/* void Shm_Get_configuration( localnode, &shmcfg )

* to the Shared Memory Configuration Table for the Cyclone CVME961.
*
* INPUT PARAMETERS:
* localnode - local node number
* shmcfg - address of pointer to SHM Config Table
*
* OUTPUT PARAMETERS:
* *shmcfg - pointer to SHM Config Table
*
* NOTES: CVME961 target system has onboard dual-ported memory. This
* file uses the USE_ONBOARD_RAM macro to determine if this
* RAM is to be used as the SHM. If so (i.e. USE_ONBOARD_RAM
* is set to 1), it is assumed that the master node's dual
* ported memory will be used and that it is configured
* correctly. The node owning the memory CANNOT access it
* using a local address. The "if" insures that the MASTER
* node uses a local address to access the dual-ported memory.
*
* The interprocessor interrupt used on the CVME961 is generated
* by the VIC068. The ICMS capablities of the VIC068 are used
* to generate interprocessor interrupts for up to eight nodes.
