It turns out my problem had to do with the ctypes representation. If I use memmove to move to move the c_char_p to a c_int, then I end up with the correct results printing out. This can be seen done in the completed code below.
from ctypes import *
from ctypes.wintypes import *
import struct
OpenProcess = windll.kernel32.OpenProcess
ReadProcessMemory = windll.kernel32.ReadProcessMemory
CloseHandle = windll.kernel32.CloseHandle
PROCESS_ALL_ACCESS = 0x1F0FFF
pid = 3112
address = 0x2411918
buffer = c_char_p(b"The data goes here")
val = c_int()
bufferSize = len(buffer.value)
bytesRead = c_ulong(0)
processHandle = OpenProcess(PROCESS_ALL_ACCESS, False, pid)
if ReadProcessMemory(processHandle, address, buffer, bufferSize, byref(bytesRead)):
memmove(ctypes.byref(val), buffer, ctypes.sizeof(val))
print("Success:" + str(val.value))
else:
print("Failed.")
CloseHandle(processHandle)
