This file contains changes made to the mmap.dll since version 1.00.
22/10/1998 NEW: Released public version 1.00.
14/11/1998 NEW: It needs at least fixpack 6 or 38 (for warp 3)
FIX: There was a bug affecting multithreaded programs which
use mmap() from more than one thread and register an
exception handler for each thread.
20/11/1998 NEW: mmap() duplicates filehandle of mmaped file
NEW: It can now use HighMemory on Warp Server Advanced SMP
and Aurora Beta
24/11/1998 NEW: All I/O operations are done with 32Kb blocks and
getpagesize() returns 32Kb. This is a GREAT speedup.
10/01/1999 NEW: Released public version 1.10
08/08/1999 NEW: MAP_SHARED supported inside same address space.
FIX: High Memory use on WSA SMP and Aurora was broken since
24/11/1998. DosAllocMem() rounds requests to a 4Kb boundary
if you request HighMemory :-|
FIX: No more use of autoregistering feature for mmap(), so there
is no more a minimum fixpack needed to be able to use
mmap() services. It should work on Warp 3. Tested on Warp 4 no
fp, Warp 4 fp 6 and 9 and Aurora Beta and GA.
NEW: mregister() and mderegister() to access mmap() services.
NEW: No more 64 maximum threads using mmap() services per process
limit.
FIX: mmap() could have left a duplicated file handle open in case of
failure in mmapping it.
NEW: Released public version 1.75.
14/08/1999 NEW: MS_ASYNC and
NEW: MS_INVALIDATE are fully supported.
21/08/1999 NEW: Released public version 1.77.
