My point is that, whatever mmap is doing, your own code
is doing *exactly the same thing*. Passing the
INVALID_HANDLE_VALUE as both your code and the mmap
code are doing is documented as producing an
WowYou put some detail in this response. Thanks so much!
I think I want to stay away from mmap because it uses the disk to
store my memory. I am trying to stay away from that. I am building
strip charts in this python project to view my data. Currently, I am
using a file and I have to open the

memory. And shared memory use physical memory.
The difference is OS an not Python

Hello Everyone,
I am getting shared memory in python using the following.
szName = c_char_p(name)
hMapObject = windll.kernel32.CreateFileMappingA(INVALID_HANDLE_VALUE,
None, PAGE_READONLY, 0, TABLE_SHMEMSIZE, szName)
if (hMapObject == 0):
print "OpenKey: Could not open nam
