<class 'OverflowError'>: int too long to convert

Question

Im trying to read memory of a program but I get error it says

from ReadWriteMemory import ReadWriteMemory

rwm = ReadWriteMemory()

process = rwm.get_process_by_name("Tutorial-x86_64.exe")
process.open()

baseaddress = 0x100000000+0x00325A70

pointer = process.get_pointer(baseaddress, offsets = [0x598, 0x28, 0x8, 0xF8, 0x18, 0x18, 0x7F8])
print(process.read(pointer))

Traceback (most recent call last):
  File "C:UsersuserDesktopprogramfrom ReadWriteMemory import ReadWriteMem.py", line 10, in <module>
    pointer = process.get_pointer(baseaddress, offsets = [0x598, 0x28, 0x8, 0xF8, 0x18, 0x18, 0x7F8])

Your version of ReadWriteMemory is too old. This was fixed in September of 2020. You might try pip install --upgrade ReadWriteMemory. If that doesn’t bring in the latest, then you’ll need to edit the package, to apply the two changes to __init__.py shown in this patch to add ctypes.c_void_p(...).
