The problem is that the min3 function is compiled as a generic function that uses generic comparison (I thought this uses just IComparable, but it is actually more complicated – it would use structural comparison for F# types and it’s fairly complex logic). > let min3(a, b, c) = min a (min b c);; val … Read more
Having added the inline to the function definition in the .c file is just superfluous. Your compilation unit of the .c file sees an extern declaration (without inline) and an inline definition. Thus it emits the symbol for the function in the object file. All other compilation units only see an extern declaration, and so … Read more
The inline keyword really just tells the linker (or tells the compiler to tell the linker) that multiple identical definitions of the same function are not an error. You’ll need it if you want to define a function in a header, or you will get “multiple definition” errors from the linker, if the header is … Read more
Programatically at run-time, You cannot. And the truth of the matter is: You don’t need to know An compiler can choose to inline functions that are not marked inline or ignore functions marked explicitly inline, it is completely the wish(read wisdom) of the compiler & You should trust the compiler do its job judiciously. Most … Read more
According to the manual, passing -std=gnu11 enables C99 instead of GNU inline semantics. This means inline, static inline and extern inline all behave differently. In particular, inline expects an external definition in a separate translation unit (which you can provide without duplicating the definition – see this answer).
To restate what I said in those little comment boxes. In particular, I was never talking about inlin-ing: // foo.h: static void f() { // code that can’t be inlined } // TU1 calls f // TU2 calls f Now, both TU1 and TU2 have their own copy of f – the code of f … Read more
Avoiding the cost of a function call is only half the story. do: use inline instead of #define very small functions are good candidates for inline: faster code and smaller executables (more chances to stay in the code cache) the function is small and called very often don’t: large functions: leads to larger executables, which … Read more
Is it possible loading an external font with inline css? NOT with an external CSS file [….]. Yes, you can base64 encode a font or fonts as shown in this article from Stephen Scaff and drop them into a style block in your page to avoid the external request. It may also be possible to … Read more
The inline keyword indicates that a function definition should be inserted inline into any code which uses it. Most of the time, this will not have any effect on the type of the function. However, in rare cases, it can lead to a function which has a more general type, since there are constraints which … Read more
The former (using inline) allows you to put that function in a header file, where it can be included in multiple source files. Using inline makes the identifier in file scope, much like declaring it static. Without using inline, you would get a multiple symbol definition error from the linker. Of course, this is in … Read more
