I want to learn the BSD-style of malloc-ing and in particular the use of vm_allocate. How do you look up where a particular source file or header file is located ?

Is loading it through dynamic C++ classes platform dependent? And lastly, how do I create a dynamic library with Xcode? Most Darwin-like systems (including Darwin) have standardized on the dlopen(3) interfaces. As to how XCode creates dynamic libraries, you should probably ask on another list. Down here we use libtool or $(CC) -dynamiclib. This email sent to site_archiver(a)lists.apple.com

Apple provides a tool, why not go the next step and provide a high level Cocoa or C interface? I already too much spent time wrapping authopen in Cocoa and running it using NSTask. I didn't implement the -stdoutpipe though, I'm just reading and writing whole files. This email sent to site_archiver(a)lists.apple.com
