You should never deploy a zero linked binary, and zero link no longer exists on 10.5 (and nobody misses it IMHO). dyld: Library not loaded: /Developer/Library/PrivateFrameworks/ZeroLink.framework/Versions/A/ ZeroLink Referenced from: /myProject/myApp Reason: image not found Trace/BPT trap The dylib will be installed in /usr/lib/ so I can give path "/usr/lib/libMyDylib.dylib". Yes it is a good idea. Currently both are in different folders and I am giving "./" path in both (dylib and app) and generating same key. I hope it would work. Thanks a lot.

wrote: Thanks. The problem I have to give file path to generate key. How will I ensure that the path I am giving will work always to generate the same key? I have one application and another is dynamic library and I want to generate the same key in both to use. On Mon, Dec 1, 2008 at 12:56 AM, Luke Hiesterman <luketheh@apple.com

wrote: Why exactly do you want to avoid ftok? It's a good way to generate shared keys. It's always possible to generate an integer key some other way yourself and then you just have to figure out how to communicate it across processes. You could write it to a file or send it over a socket. On Nov 30, 2008, at 3:25 AM, Rakesh Singhal <rakesh.singhal@gmail.com

It is declared in semaphore.h but when I do man sem_init() then it gives the message "No manual entry for sem_init". Now, I am using sem_open(). I think it is right API to create unique semaphore between multi-processes. But creating it in one process if I try to create in another process, the value of semaphore is not same. I am using same name in both process(1st argument of sem_open()). Please suggest to create semaphore (cross-processes). Use either POSIX named semaphores, or use System V semaphores: This email sent to site_archiver@lists.apple.com
