How to get some comfort with threads?

[uprinz]

Hi!

I'd like to give some debug while system starts up. With dvice drivers
it is easy as the dev->dev_name gives an easy access to the devices name.

But with threads I don't know how to get the name of a thread.

I can do something like this:
if( NutThreadCreate("isAlive", isAlive, 0, 256))
     printf("Thread isAlive started\n");

if( NutThreadCreate("display", display, 0, 512))
     printf("Thread display started\n");

But I'd like to may be use a function to start up the thread and report
success or error by giving the name to the debug output.
Ah, and I don't like to search for an ID in a list or something like that.

And has someone any idea how to find out why a thread has died?

Any idea?

Best regards, Ulrich

If you've got thread handle:

HANDLE th;

then it's easy to get the name of that thread:

const char *name = ((NUTTHREADINFO *) th)->td_name;

See for example the source code of system function NutThreadWake(),
everything will be clear. Also see NutDumpThreadList().

To do opposite conversion (map name to thread handle), just call
GetThreadByName().

If the only time you need it is for thread creation then why not do the
following?

HANDLE myThreadCreate(const char * name, thread_f * tf, void * arg, int
stack_sz) {    HANDLE th;
    th = NutThreadCreate(name, tf, arg, stack_sz);
    printf("Creating thread \"%s\" %s\n", name, th ? "succeeded" :
"failed");
    return th;
}

or if you need the name at some later time then do what Adam Dybkowski said.
