the problem occurs when restype is not None, but c_int. E.g.
if hasattr(_libs['grass_gis'], 'G_set_error_routine'):
G_set_error_routine = _libs['grass_gis'].G_set_error_routine
G_set_error_routine.restype = c_int
G_set_error_routine.argtypes = [CFUNCTYPE(UNCHECKED(c_int),
String, c_int)]
errtype = CFUNCTYPE(UNCHECKED(c_int), String, c_int)
errfunc = errtype(print_error)
or
errtype = CFUNCTYPE(c_int, String, c_int)
errfunc = errtype(print_error)
ends up with error
G_set_error_routine(errfunc)
TypeError: in method 'G_set_error_routine', argument 1 of type 'int (*)
(char const *,int)'
The first argument of CFUNCTYPE defines result type (restype), AFAIU
that should work.
Thanks in advance again, Martin
