UNIX for Advanced & Expert Users

Hello,

We are working on a product which requires library interposing. And
according to the market requirements, needs to be migrated on AIX OS also.
So now, the question is "Is library interposing possible in AIX?" If yes,
how? If no, then what are the other alternatives?

As per my information Library Interposing is possible in Sun Solaris, Linux
operating systems.

Appreciate if any guidance/reference is provided in this regard.

PS : For details on the Sun Solaris library interposing, you may refer to
the following document:

Since you provided the link, I don't get your problem.

Yes it is possible. You define an environment variable, LD_PRELOAD, to point to a library that has entrypoints (functions with the same names as) like those you have in your executable. Usually it's libc functions like maybe printf. But it could be interposing functions in a library you've created with those in yet another library...

Hello Jim,

Thanks for the reply.
I am not conversant with AIX commands, can you please guide me in detail how i should carry this activity.

Is there any other name in AIX for library interposer?


Regards
