Hello,
I have a cdef'ed class with a cdef'ed method that looks something like this:
cdef class MyClass:
cdef void myfunc(self, double *x):
... (function contents) ...
def execute():
call_func( &(self.myfunc) )
I'm linking to a function in an external library that accepts a
function pointer of similar signature
cdef extern from 'somelibrary.h':
cdef void call_func(void (*func)(double *x))
However, I receive an error at compile time that a function of type
void (*)(MyClass, double *)
cannot be converted to a function of type
void (*)(double *)
I was wondering there is a way to unbind this myfunc class method so
that it can be properly sent to this external function. I know that I
can simply create a function pointer attribute as part of the class
but it would seem cleaner for a user to subclass and override myfunc
instead of subclassing and setting the value of function pointer
attribute from within an overridden __cdef__ method.
Thank you in advance for any hints or suggestions!
