Gather: What exactly are the requirements? The docs say "a function that will gather the data - called .out()" What are the requirements on the return type? Further in scenarios_code.html#scenarios_code_mon there is the definition void *out(const char* msg) { m_msg = msg; return this; } Is out() called implicitly or not? Why is "this" returned as a void*? Confused...
The requirements are to return a void* pointer. This is needed when http://torjo.com/log2/doc/html/caching.html and you want to cache the filter as well.
If I remove the usage of http://torjo.com/log2/doc/html/caching.html#caching_BOOST_LOG_BEFORE_INIT_CA... then you can return anything you like. For more details, please take a look at cache_before_init_macros.hpp, line 50
I just thought of a way to avoid this requirement. if(!is_enabled); else for(int i = 0; i == 0;) for(bool (*f)(); i < 3; ++i) if(i == 0) { struct local { bool do_filter() { return(/is_enabled/); } }; f = &local::is_enabled; } else if(i == 2) { // cache filter. } else //do logging Wow, that's brilliant!
