Hi,

This file:

https://xenomai.org/documentation/xenomai-3/pdf/xeno3prm.pdf

makes several references to pthread_self() which implies that's the way 
to do what you are looking for here.

However (to your point), it doesn't explicitly document (in section 6.60 
Thread management) pthread_self() itself, whereas this file:

https://xenomai.org/documentation/xenomai-2.6/pdf/posix-api.pdf

in section 3.12.3 documents pthread_self() along with pthread_create() 
and the other "POSIX thread management" functions.

Perhaps when the 3.0 documentation was written, there was a decision 
made to not document any of the "standard POSIX thread management" 
functions unless there was also an RT variant of the function (sitting 
behind a wrapper) which had behaviour beyond what one could expect to 
find in the standard (non RT) POSIX documentation.  Perhaps there's a 
statement to that effect somewhere in the Xenomai-3 documentation, and 
if not, maybe there should be.

Regards,
Steve
