Calling a c library function from within ctypes python












0















Using nm, I get these functions back from my library (pasted at end).
I want to call the function "__Z13librador_initv" using ctypes in python... but using "print(libraryname.__Z13librador_initv)" is not getting me anywhere. Anyone know how to do this successfully? Do I need to use the hex number?



It appears to import the actual library ok using this code:
from ctypes import *
testlib = cdll.LoadLibrary("librador.1.0.0.dylib")



0000000000004bc0 T __Z13generator_sind



0000000000004120 T __Z13librador_exitv



0000000000004080 T __Z13librador_initv



0000000000004b70 T __Z13round_to_log2d



0000000000004c10 T __Z16generator_squared



0000000000004c40 T __Z18generator_sawtoothd
