.Sh DESCRIPTION
|
|
The

.Fn pthread_getname_np
|
|
functions retrieve the
|
|
.Fa name
|
|
associated with
|
|
.Fa thread .
|
|
If
|
|
.Fn pthread_set_name_np
|

the buffer pointed to by
|
|

.Sh ERRORS
|

|
Because of the debugging nature of
|
|

|
|
functions, all errors that may
|
|

.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.
