Notes
This call tells application in which bank the memory area requested is free for allocationprovides a release of a contiguous explicit memory area previously allocated. Partial release of allocated memory is possible. Refer to explicit memory allocation for further informations. This system call is only available in OZ release V4.6 and newer.
