libcurl is C, not C++. It does not throw exceptions. An
actual C++ exception would likely be a problem in your code.

Check the pointer return for validity.

That is not a URL.
Check the return status code.

Check the return status code.
Binding a share object to the easy handle will disable the
   use of the multi objects shared data (dns, cookie, etc.)

Check the status code.

Check the status codes. Assuming libcurl launched
GET against 'http://primorye.ru/', the above will
have handles in various states of incompleteness.
Should be handled cleanly below, perhaps not.

Check the status code.
