Sorry about the confusion... the "main" symbol does not appear
to work for this illustration (possibly because it doesn't come from a
dynamic library?). If I try with "errno" instead, I get
raw : ~ $ ./dltest
Handle: 0x2805e000, errno: 0x280f5cd4
Handle: 0x0, errno: 0x0
raw : ~ $
--- according to the manpage for dlsym(), passing 0 for handle should
have the same effect as passing 0 as the path to dlopen; i.e, to
access the symbol table for the running program.
