 Gotcha works by rewriting the Global Offset Table (GOT) that links inter-library callsites and variable references to their targets. 
 Because of this Gotcha cannot wrap intra-library calls (such as a call to a static function in C) or calls in statically-linked binaries. 
 Binary rewriting technology such as DyninstAPI (https://github.com/dyninst/dyninst) is more appropriate for these use cases.
+Additionally, the function pointer wrapping feature with GOTCHA only applies to function pointers created after wrapping functions.
+The function pointers created before wrapping would not be wrapped by gotcha.
