shared memory pointer

[Tim]

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
