Shashi,
Can you elaborate on your use case? There's really not enough
information to understand what you're trying to accomplish to know how
to help.
Assuming that you are using LD_PRELOAD to "link the vcom library to the
application", the vcom api layer redirects calls based on the fd to
either vppcom or libc.
Also what version of the code are you running?
You should be aware that VCL/LD_PRELOAD is still largely experimental
and under development. There are many features of the posix socket
interface which are missing or have stub implementations. Development
of VCL to date has been entirely use-case driven.
Thanks,

Hi
I have a linux application which uses native kernel epoll_wait calls.
I needed to add a new thread in that application which is a VPP based
thread i.e. it uses DPDK to send and receive on additional igb_uio
ports. For this I had to link the vcom library to the application and
now I see that epoll used by all linux application is from vcom. How
do I separate out linux thread from VPP thread to use corresponding
epoll libraries
