How to make a file which is both shared library and executable

[durgaprasad jammula]

Hi All,

   I want to make a shared library which should also be an executable. Can you 
please tell me how to do it.

     For example, in linux, consider /lib/libc.so.6. We can execute that as a 
command and we can use that also as a shared library.

   Even I want to make my libraries like that. Can you please help me?

Thank you in advance
