Hi gurus,
I wrote a multithread application by pthread and bind the threads with specific
cpu cores by processor_bind(), now I am wanting to confirm if the binding is
effective. I wonder if there is a system call to return the current core_id of
a certain thread? I failed to get the answer by
Look at the PBIND_QUERY flag in processor_bind(2). The manpage
suggests (though it's not as clear as it could be IMO) that it will
return the current binding into the processorid_t structure pointed to
by the 4th parameter.

Do you mean that if the third parameter is PBIND_QUERY while the last parameter
is not NULL (obind here), the binding processorid structure will be stored in
the last processorid_t obind? Then, I could read it...

That is what the manpage suggests. Looking at the source, it looks
like that's what it does as well.
