Thread: When to stop?

So, while learning C++ from the stroustrup's book i often wandered this.

At some point of the book, "inline" keyword is introduced in the book, it is described a little with no examples.

So, should i just read the text about inline from the book, understand the text and stop there?

Or should i for example try and google "inline" keyword to see what more information can i find out about the topic? When exactly should i stop learning about the "inline" keyword in this case?

Is it best to just remember the basic idea of inline, and when in the future you need something like that, you just dig out documentation and read it then? The point is to know that something exists, and the details aren't that important?

In simplest terms, inline functions are meant to replace #defines.

I stopped using inline b/c there is no guarantee the compiler will or will not inline your code. The process to go through to figure out if the compiler will or will not inline your code is complex and varies from compiler to compiler. And on a modern processor the benefit between inline and non-inline may not be worth the hassle.
