site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com I looked at the source for an objective-c runtime file: http://darwinsource.opendarwin.org/10.3/objc4-235/runtime/objc-class.m You can see there two non-static functions: void instrumentObjcMessageSends (BOOL flag) void logObjcMessageSends (ObjCLogProc logProc) However, I get an unresolved reference to logObjcMessageSends.

From my read of the source, you would need to call both functions: instrumentObjcMessageSends(YES); logObjcMessageSends(myProc); Can anyone shed light on this?

[I also downloaded the 10.4.1 source, and these files are the same. For some reason you cannot get at the source for this release as easily.] if I use instrumentObjcMessageSends in my project, it builds and links just fine (static not ZeroLink). What makes this second function so intriguing is that you can specify your own logging function, which could also filter the output based on programmatic runtime criteria. But, without the reference to logObjcMessageSends all is lost. What one DOES get with the first function is a log of EVERY method/class call. In a few seconds I got about 10Megs worth of data. Clearly a filter here would be of great value. This email sent to site_archiver@lists.apple.com
