Support for CFFI. Allows checking whether objects are CFFI functions and obtaining the pointer and numba signature.
Get a pointer to the underlying function for a CFFI function as an integer.
Get the numba signature for a CFFI function
Check whether the obj is a CFFI function
D.__contains__(k) -> True if D has a key k, else False
Map CFFI type to numba type
Convert a ctypes type to a numba type
Convert a ctypes value to a numba type
Check whether the given value is a ctypes value
