>>> objMmap = mmap.mmap(fHdl,os.fstat(fHdl)[6])
Traceback (most recent call last):
File "<pyshell#21>", line 1, in -toplevel-
objMmap = mmap.mmap(fHdl,os.fstat(fHdl)[6])
OverflowError: memory mapped size is too large (limited by C int)
>>> os.fstat(fHdl)[6]
4498001104L
Max. allowed value is here 256*256*256*128-1
i.e. 2147483647
'jurrasic' lets greet us also in Python.
The only existing 'workaround' seem to be,
to go for a 64 bit machine with a 64 bit Python version.
No other known way?
Can the Python code not be adjusted, so that C long long is used instead of
C int?
