I don't know if what you want is to set the actual name of the thread
in the kernel sense (ie, the name that shows up in /proc) or if
pthread keeps its own data structures with logical thread names, but
prctl does set the names for individual threads (ie, for the specific
PID corresponding for each different thread started by a process) when
called from within the thread. (I'm referring to the specifc names
that show up in
/proc/$PID/task/$TID/stat).

Hope that helps!
