Given our previous conversation, it will probably be easier to use
ctypes to get the function handles for dynamically loaded libraries
and *somehow* get that function pointer into Cython.
My attempt is like so (for a simple example) but Cython is complaining
during compilation:
from ctypes import *
cdef extern from "Python.h":
void* PyLong_AsVoidPtr(object)
cdef int a
libc = CDLL('libc.so.6')
timefunc = libc.time
cdef object tptr = ctypes.addressof(timefunc)
cdef int (*mytime)()
mytime = PyLong_AsVoidPtr(tptr)
a = mytime[0]()
print a
Error converting Pyrex file to C:
------------------------------------------------------------
...
libc = CDLL('libc.so.6')
timefunc = libc.time
cdef object tptr = ctypes.addressof(timefunc)
cdef int (*mytime)()
mytime = PyLong_AsVoidPtr(tptr)
^
------------------------------------------------------------
/home/brucewayne/Desktop/cytypestest.pyx:13:25: Cannot assign type
'void *' to 'int (*)(void)'
Any ideas how to get that at that pointer? I'm open to ideas that
involve the use of really big hammers ;)
Cheers!
Chris
