thanks for the reply...

i was browsing the code..so i found this..please confirm

1) When from my client program I call curl_easy_perform() it uses normal
send() on tcp socket to write data.

2) then it changes state and pass fd to poll() to wait for response message.

3) once response is received it stores it in some buffer.

4) state is again changed.

now after the transfer is success, is fd removed from poll(). After this
transfer is done, I want to use the fd for some other purpose.

After this if some message comes on fd then will curl invoke poll() and
hence read operation?
