 .SS "lwpctl"
 .LP
 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
 \fBctl\fR file.
+.SS lwpname
+A buffer of \fBTHREAD_NAME_MAX\fR 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
+\fBTHREAD_NAME_MAX\fR 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. \fBTHREAD_NAME_MAX\fR may increase
+in the future; clients should be prepared for this.
 .SS "lwpstatus"
 .LP
 lwp-specific state information. This file contains the \fBlwpstatus\fR
 structure for the specific lwp as described above for the representative lwp in
 the process's \fBstatus\fR file.
