libpthread_dbg(3) deletion from the base distribution 

libpthread_dbg(3) is a remnant library from the M:N thread model
(pre-NetBSD-5.0) API to introspect threads within a process and for use
of debuggers.

Currently in the 1:1 model it's not used in GDB neither in LLDB and it's
not either planned to be used. It's current function to read pthread_t
structures is realizable within a regular debugger capable to
instrospect objects within a tracee (GDB, LLDB...).

Remaining users of this API can still use this library from
pkgsrc/devel/libpthread_dbg.

.Os
.Sh NAME
.Nm pthread_dbg
.Nd POSIX Debug Threads Library
.Sh LIBRARY
.Lb libpthread_dbg
.Sh SYNOPSIS
.In pthread_dbg.h
.Pp
.Nm cc
.Op Ar flags
.Ar files
.Fl lpthread_dbg
.Op Ar libraries
.Sh DESCRIPTION
The
.Nm
library provides an implementation of the standard
.Tn POSIX
threads library debugging facilities.
.Pp
The
.Nx
implementation is based on 1:1 thread model, therefore each
.Xr pthread 3
has a kernel thread, called a light-weight process (LWP).
.Pp
Note that the system private thread interfaces upon which the
.Xr pthread 3
library is built are subject to change without notice.
In order to remain compatible with future
.Nx
releases, programs must be linked against the dynamic version of the
thread library.
Statically linked programs using the
.Tn POSIX
threads framework may not work when run on a future version of the system.
.Pp
The
.Nm
library is designed to be used in debuggers and to control and introspect the
.Nx
implementation of the
.Tn POSIX
threads.
Software may use native
.Tn LWP
threads without
.Xr pthread 3
layer,
in that case
.Nm
cannot be used.
.Ss Error codes
The following error codes are defined in
.Nm
functions:
.Pp
.Bl -column ".Sy TD_ERR_BADTHREAD" "Request is not meaningful for that thread" -compact
.\".It Sy "Symbol" Ta Sy "Descriptive name"
.It Dv TD_ERR_OK Ta "Success"
.It Dv TD_ERR_ERR Ta "Generic error"
.It Dv TD_ERR_NOSYM Ta "Symbol not found (proc_lookup)"
.It Dv TD_ERR_NOOBJ Ta "No object matched the request"
.It Dv TD_ERR_BADTHREAD Ta "Request is not meaningful for that thread"
.It Dv TD_ERR_INUSE Ta "The process is already being debugged"
.It Dv TD_ERR_NOLIB Ta "The process is not using libpthread"
.It Dv TD_ERR_NOMEM Ta "Memory allocation failed"
.It Dv TD_ERR_IO Ta "A callback failed to read or write"
.It Dv TD_ERR_INVAL Ta "Invalid parameter"
.El
.Sh FUNCTIONS
The following functions comprise the core of the
.Nm
library:
.Bl -column -offset indent "td_thr_getname(3)" "convert the pthread_t to a thread handle"
.It Sy Function Ta Sy Description
.It Xr td_close 3 Ta close connection to a threaded process
.It Xr td_map_pth2thr 3 Ta convert a pthread_t to a thread handle
.It Xr td_open 3 Ta make connection to a threaded process
.It Xr td_thr_getname 3 Ta get the user-assigned name of a thread
.It Xr td_thr_info 3 Ta get information on a thread
.It Xr td_thr_iter 3 Ta iterate over the threads in the process
.El
.Sh SEE ALSO
.Xr pthread 3
.Sh STANDARDS
The
.Nm
library is a
.Nx
extension.
.Sh HISTORY
The
.Nm
library first appeared in
.Nx 2.0
along with the Scheduler Activation thread interface.
This interface was authored by
.An Nathan J. Williams
and merged by
.An Jason R. Thorpe .
In
.Nx 5.0
the
.Nm
library was moved to the new 1:1 thread model.
.Sh AUTHORS
.An -nosplit
.An Nathan J. Williams Aq Mt nathanw@NetBSD.org
.Pp
This manual page was written by
.An Kamil Rytarowski Aq Mt kamil@NetBSD.org .
.Sh BUGS
It is not possible to debug the
.Nx
library with a debugger that is using
.Nm
internally.

.It Dv TD_STATE_RUNNING Ta "Thread is alive"

.El
.Pp
It is not possible to retrieve information whether a thread
is suspended or resumed using this interface,
as this data is stored only inside the kernel and not in the
.Dv pthread_t
object.
The
.Dv TD_STATE_RUNNING
name is kept for backwards compatibility with old Scheduler Activation threads.
The
