libffi for the iPhone

=

**[libffi](http://sourceware.org/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.

Calling functions

-

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.

You can however retarget existing functions if you have a function pool. See [Tim Burks' post about Nu's method pool](http://stackoverflow.com/questions/219653/ruby-on-iphone), see [JSCocoa's Burks Pool](http://github.com/parmanoir/jscocoa/blob/master/JSCocoa/iPhone/BurksPool.m) for another implementation.

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.
