-.SH NAME
-/proc/pid/task/, /proc/tid/, /proc/thread\-self/ \- thread information
-.SH DESCRIPTION
-.TP
-.IR /proc/ pid /task/ " (since Linux 2.6.0)"
-.\" Precisely: Linux 2.6.0-test6
-This is a directory that contains one subdirectory
-for each thread in the process.
-The name of each subdirectory is the numerical thread ID
-.RI ( tid )
-of the thread (see
-.BR gettid (2)).
-.IP
-Within each of these subdirectories, there is a set of
-files with the same names and contents as under the
-.IR /proc/ pid
-directories.
-For attributes that are shared by all threads, the contents for
-each of the files under the
-.IR task/ tid
-subdirectories will be the same as in the corresponding
-file in the parent
-.IR /proc/ pid
-directory
-(e.g., in a multithreaded process, all of the
-.IR task/ tid /cwd
-files will have the same value as the
-.IR /proc/ pid /cwd
-file in the parent directory, since all of the threads in a process
-share a working directory).
-For attributes that are distinct for each thread,
-the corresponding files under
-.IR task/ tid
-may have different values (e.g., various fields in each of the
-.IR task/ tid /status
-files may be different for each thread),
-.\" in particular: "children" :/
-or they might not exist in
-.IR /proc/ pid
-at all.
-.IP
-.\" The following was still true as at kernel 2.6.13
-In a multithreaded process, the contents of the
-.IR /proc/ pid /task
-directory are not available if the main thread has already terminated
-(typically by calling
-.BR pthread_exit (3)).
-.TP
-.IR /proc/ tid /
-There is a numerical subdirectory for each running thread
-that is not a thread group leader
-(i.e., a thread whose thread ID is not the same as its process ID);
-the subdirectory is named by the thread ID.
-Each one of these subdirectories contains files and subdirectories
-exposing information about the thread with the thread ID
-.IR tid .
-The contents of these directories are the same as the corresponding
-.IR /proc/ pid /task/ tid
-directories.
-.IP
-The
-.IR /proc/ tid
-subdirectories are
-.I not
-visible when iterating through
-.I /proc
-with
-.BR getdents (2)
-(and thus are
-.I not
-visible when one uses
-.BR ls (1)
-to view the contents of
-.IR /proc ).
-However, the pathnames of these directories are visible to
-(i.e., usable as arguments in)
-system calls that operate on pathnames.
-.TP
-.IR /proc/thread\-self/ " (since Linux 3.17)"
-.\" commit 0097875bd41528922fb3bb5f348c53f17e00e2fd
-This directory refers to the thread accessing the
-.I /proc
-filesystem,
-and is identical to the
-.IR /proc/self/task/ tid
-directory named by the process thread ID
-.RI ( tid )
-of the same thread.
