(It’s called the dyld_shared_cache.) The standard APIs to access shared libraries (e.g., dlopen) translate library pathnames to the appropriate entries in the cache.<div><br></div><div>So, the library files do not exist in the filesystem but, if you use the standard APIs, they appear to exist. And, that’s what you’re seeing below.<br><br><div>
