QUESTION
Sending POST request using libcurl C++. I have tried almost all combination except the right one which I could not figure out.
...ANSWER
Answered 2017-Jul-07 at 10:34I would prefer using custom request here CURLOPT_CUSTOMREQUEST
below is the code snippet that works fine!

ANSWER
Answered 2017-Apr-20 at 09:11Method 1 and 2 are equivalent since Protobuf messages don't overload operator&
.
Protobuf manages lifetimes (and I think Copy-On-Write semantics) internally, so I'd favour value semantics throughout.
I'm never exactly sure whether (and how) ownership is transferred with the allocated setters (set_allocated_*
). If you find a source that documents it, please tell me!
Iff set_allocated_profile
takes ownership of the pointer, then neither of your approaches is correct. You'd need to release the pointer from your owning shared pointer (see How to release pointer from boost::shared_ptr?).
Iff set_allocated_profile
does not take ownership, I'd prefer to write:
