I am wondering about the symantics. If I load a.so which defines 'a'
and then load b.so which redefines 'a', which definition will be seen
when I subsequently load c.so which needs 'a' ?

It should be _really_ easy to write a small test program for that.Quote:> I'm so pleased to see RTLD_GLOBAL is working in ld.so-1.7.12!

Anyway, is there some written document that actually says what the
semantics are? Doo we care? ;-)
My view: the a in c should refer to the a in b. If you don't want that,
don't load b with RTLD_GLOBAL...

1. strange streams socket symantics
I have written three programs that communicate with each other through
INET streams sockets---
prog A
listens on port X
listens on port Y
prog B
listens on port X
connects to prog A on port Y
prog C
connects to prog A on port X
connects to prog B on port X
I had a lot of trouble with this until I found out about SO_REUSEADDR.
:-) Anyway, I'm still having occational problems. Sometime, prog C
will think its connected to prog B while prog B will still be blocking
in select. I'm fairly sure all the fd masks are set correctly because
this problem only happens sometimes.
Is there something I may not be doing? Is there I man page I missed? I
suppose I should check to see if my threads package is messing things
up somehow.
thanks,

3. BSD Symantics? Is that a kernel option?
5. has anyone successfully used dlopen's RTLD_GLOBAL flag?
6. pipe example
7. ld.so-1.7.11 RTLD_GLOBAL working?
9. dlopen, -rdynamic, RTLD_GLOBAL ???
