More specifically, I'd like to retrieve the thread state in the LC_UNIXTHREAD load command and extract eip's value. I've found getsectdatafromheader() which requires a mach header. I've only found _dyld_get_image_header to get the mach header, however, I found nothing that retrieves a regular executable's (not a loaded shared library...) mach header. _dyld_get_image_header() should provide the executable's header itself in addition to all dylibs and bundles. If your code is compiled as part of the executable, you can use _mh_execute_header from mach-o/ldsyms.h. But that won't work if your code is part of a library or bundle. Note that the functions in mach-o/getsect.h will only look up LC_SEGMENT contents. You probably need to scan the load commands manually to find LC_UNIXTHREAD.

On BSD-based systems, it's all that's needed to implement a debugger. On Mac OS X, you also need the task port for the process being debugged, in order to access its address space contents. dtrace is a command-line command that front-ends the DTrace facility. The DTrace facility is a comprehensive dynamic tracing framework capable of instrumenting existing code without specific explicit instrumentation, including both user programs and the operating system itself.
