Re: memory management of all_visible_functions return

[Robert E. Griffith]

Is the posix standard kept on opengroup.org? I just created an account 
there and spent some time looking but have not found it yet. One link 
that I thought was going to be it prompted me to login again (I think to 
the austin group section) but my new credentials would not work for that 
login.

Should I be able to access it for free? Is there a "shell" subsection 
that bash complies with?
