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 name file mapping object"
raise WinError()
self.pData = windll.kernel32.MapViewOfFile(hMapObject,
FILE_MAP_ALL_ACCESS, 0, 0, TABLE_SHMEMSIZE)
This seems to work OK. How do I get to the data in self.pData? It is
suppose to be an array of floats. I think MapViewOfFile returns a
point to the data. Here is what I tried.
current_time = 45.55
memcpy( current_time, self.pData, 4 )
but I get an error:
ArgumentError: argument 1: <type 'exceptions.TypeError'>: Don't know
how to convert parameter 1
I need to get my floating point array casted from the self.pData. Any
help would be appreciated!
Thanks
Tim
