     lwpctl
         Write-only control file. The messages written to this file affect the
         specific lwp rather than the representative lwp, as is the case for the
         process's ctl file.
  
+    lwpname
+        A buffer of THREAD_NAME_MAX bytes representing the LWP name; the buffer
+        is zero-filled if the thread name is shorter than the buffer. If no
+        thread name is set, the buffer contains the empty string. A read with a
+        buffer shorter than THREAD_NAME_MAX bytes is not guaranteed to be NUL-
+        terminated.  Writing to this file will set the LWP name for the
+        specific lwp.  This file may not be present in older operating system
+        versions. THREAD_NAME_MAX may increase in the future; clients should be
+        prepared for this.
+ 
     lwpstatus
         lwp-specific state information. This file contains the lwpstatus
         structure for the specific lwp as described above for the
         representative lwp in the process's status file.
