Comment (by kencu):

 this looks like it will do it:

 {{{
 #include <errno.h>
 #include <pthread.h>
 #include <mach/kern_return.h>
 #include <mach/thread_info.h>
 #include <mach/thread_act.h>

 int pthread_threadid_np(pthread_t thread, __uint64_t *thread_id) {

     if (thread_id == NULL) {
         return EINVAL;
     }

     if (thread == NULL) {
         thread = pthread_self();

         if (thread == NULL ) {
           return ESRCH;
         }
     }

     mach_port_name_t port = pthread_mach_thread_np(thread);

     thread_identifier_info_data_t info;
     mach_msg_type_number_t info_count = THREAD_IDENTIFIER_INFO_COUNT;

     kern_return_t kr = thread_info(port,
                                    THREAD_IDENTIFIER_INFO,
                                    (thread_info_t)&info,
                                    &info_count);
     if(kr != KERN_SUCCESS) {
         return ESRCH;
     } else {
         *thread_id = info.thread_id;
         return 0;
     }
 }
 }}}
