Trigger function on shared module init

[rayuthar]

Hi,

I need to trigger a function, whenever my shared module (.so) gets
loaded and before its been used by application.

Any suggestions?

Thanks

Please consult a newsgroup appropriate for the operating system
and toolchain that you are using. The C language itself does not
know anything about shared modules or dynamic loading.

In SGI IRIX, this would be handled by the 'ld' option -init

On GNU at least, you can also just include a function called _init, and
the linker will use that without needing a special option.
