Abstract
Runtime code hooking techniques are described in which a place holder instruction within a compiled module is used as an entry point to enable code hooking. A hook function to modify a target function is developed. At runtime, the target function to be modified is located. A place holder instruction within the target function is overwritten with instructions to cause execution of the hook function when the target function is called.
