Where can I find dlopen, dlclose, and dlsym for AIX?

An implementation of these dynamic code loading functions was written by
Jens-Uwe Mager and can be found at

From: Gary R. Hook

Starting with AIX 4.2 a dlopen et. al. are included in the base OS in
the libdl.a library. Under AIX 4.1 this is available as SLHS (Shared
Library Hookable Symbols) as APAR IX IX71849 for the runtime package and
APAR IX IX72973 for the development tools.
