Libcurl documentation specifies that curl_easy_setopt APIs returns CURLE_OK

I would like to know if really this API can fail? Under what circumstances
it can fail?
Yes it can fail and the circumstances vary from option to option. For the
exact function I suggest you read the code!
Is the return value needs to be checked for these APIs. SInce my code has
20-30 set-opts and the code becomes lengthy.
Well, that's how C works...
Same problem is with curl_slist_append. Do i need to check the pointer
returned by this API?
Yes, if you want to survive when it returns error. That might of course be
rare, but it can still return NULL - like when out of memory.
