Frequently Asked Questions

This Section is a compilation of the most common questions via GitHub, chat, and mailing list.

Can I Encrypt CAF Communication?

Yes, by using the OpenSSL module (see Free Functions).

Can I Create Messages Dynamically?


Usually, messages are created implicitly when sending messages but can also be created explicitly using make_message. In both cases, types and number of elements are known at compile time. To allow for fully dynamic message generation, CAF also offers message_builder:

message_builder mb;
// prefix message with some atom
// fill message with some strings
std::vector<std::string> strings{/*...*/};
for (auto& str : strings)
// create the message
message msg = mb.to_message();

What Debugging Tools Exist?

The scripts/ directory contains some useful tools to aid in analyzing CAF log output.
