libffi for the iPhone
libffi allows calling any C-function or ObjC method at runtime.
libffi-iphone is a stripped down version of libffi, tailored just for the iPhone. libffi-iphone includes source code for both the iPhone simulator and the iPhone itself.
Works just like libffi.
Creating ffi closures, new functions created and called at runtime
ffi closures don't work on the iPhone, as
mprotect is disabled.
To retarget an ObjC pool method, use the method's hidden
_cmd argument (the current selector) and
[self class]. This will tell you which method of which class is being called.
libffi-iphone uses libffi's license.
