Change History (most recent first):
|
|
|
|
<8> 11/25/91 DTY Take out interface for MoveHLow() since itÕs now in
|
|
MemoryMgrPriv.h.
|
|
<7> 11/21/91 DTY Add interface for MoveHLow here since itÕs currently only used
|
|
by findFreeSessionRecord. WeÕll probably want to move it into
|
|
Memory.h someday.
|
|
<5> 12/14/90 JWM moving a bit from eppc.h to eppcPrivate.h. The bit is
|
|
registerOnNetwork (0x80000000). It is not part of the API.
|
|
<4> 11/6/90 JWM removed conditional ForB2. Added a status bit to indicate
|
|
memory restart condition when trying to deliver a message in the
|
|
scanReadBQ path. This will keep the system from breaking
|
|
connections because of failure to get memory.
|
|
<2> 10/30/90 csd Make the symbols match the BBS headers.
|
|
<0> 4/26/89 JWM New Today.
