Invoking a function of library libfprint in Python
- by Ivanelson
I need help to call a function(Struct C) that detects the devices, so I'm calling the function this way:
from ctypes import *
fp = CDLL('./libfprint.so.0')
fp.fp_discover_devs.argtypes = None
fp.fp_discover_devs.restype = c_char_p
ret = fp.fp_discover_devs()
print ret # is "0"
That is not detected any device, because the return is "0".
