We use the globally unique thread ID:
static uint64_t
GetGloballyUniqueThreadIDForMachPortID (thread_t mach_port_id)
{
kern_return_t kr;
thread_identifier_info_data_t tident;
mach_msg_type_number_t tident_count = THREAD_IDENTIFIER_INFO_COUNT;
kr = thread_info (mach_port_id, THREAD_IDENTIFIER_INFO, (thread_info_t)
&tident, &tident_count);
if (kr != KERN_SUCCESS)
{
return mach_port_id;
}
return tident.thread_id;
}
this is the best way because mach ports can be re-used, but the globally unique
thread ID is always guaranteed to be unique.
