.Sh DESCRIPTION
The
.Fn pthread_set_name_np
and
.Fn pthread_setname_np
functions apply a copy of the given
.Fa name
to the given
.Fa thread .
.Pp
The
.Fn pthread_get_name_np
and
.Fn pthread_getname_np
functions retrieve the
.Fa name
associated with
.Fa thread .
If
.Fn pthread_set_name_np
was not previously called for
.Fa thread ,
the buffer pointed to by
.Fa name
will be empty.
.Sh ERRORS
The
.Nm pthread_getname_np
and
.Nm pthread_setname_np
will fail if
.Bl -tag -width Er
.It Bq Er ESRCH
No thread could be found in the current process corresponding to that
specified by the given thread ID
.Fa thread .

Because of the debugging nature of
.Nm pthread_get_name_np
and
.Nm pthread_set_name_np
functions, all errors that may
appear inside are silently ignored.

.Sh STANDARDS
.Fn pthread_set_name_np
and
.Fn pthread_get_name_np
are non-standard extensions.
.Fn pthread_setname_np
and
.Fn pthread_getname_np
are also non-standard, but are implemented by larger number of operating
systems so they are in fact more portable.
