>Description:
        The functions pthread_attr_getscope() and pthread_attr_setscope() are 
defined in the headerfile and supported by libpthread,
        but they are missing in the manuals.
        Even if the flag value that they maintain, there should be a manual for 
them.
        Some manual fragments seems to be in the pthread_attr.3 manual, but 
they are commented out.
        The interesting question why I've started searching for it is the 
behaviour - including the default setup for this flag.
        It looks to me like that all threads are mapped to lwp's and so are of 
SCOPE_SYSTEM, but it should be stated somewhere.
>How-To-Repeat:
        Try to find a manual for theese function - you will be out of luck.
>Fix:
        Add the missing manual-parts to pthread_attr.3 manual.
        I cannot give you a patch here, because I don't know the exact 
behaviour of the threads in NetBSD - sorry.
