interpose | Minimalist net/http middleware for golang | HTTP library

The comments given to the Q are very relevant.

First, as Remy Lebeau stated, the WM_HSCROLL message tells you if the operation is done:

Those characters all have special meaning in Clojure and you simply can not enter them just with the quote. So they are handled with their meaning by the reader and then your ' quote is used for the next form. This all will lead to code that calls the one-arity version of interpose, which then will give you a transducer, thus resulting in the functions you see as results.

If you want to have those characters as symbols, you can use symbol. E.g.

println always returns nil. You can get what you want by using with-out-str as follows:

You say a.dylib depends on b.dylib but b.dylib does not depend on a.dylib and that you want no calls in b.dylib to ever be interposed. You gave open as an example of an interposed function.

The example I gave was that a.dylib needs to call processFile that is defined in b.dylib and it opens files. You don't want the open call in b.dylib to be interposed ever (whether a.dylib is loaded or not).

The only way I know to pull this off is for processFile to dynamically load the C library instead of letting ld do it automatically.

There are two problems with this approach. The first is that each function that needs to call open will need one additional if statement to execute the code to resolve the symbol.

The other is that you need to know ahead of time the filename of the C library to load. And if there's a problem resolving the symbol, then you have to deal with a situation that most programs don't have to deal with; at least at a later time.

The code will look something like this:
