I see. Well, think "inline" function like another form of macro. So,
they are inlined at the point they are called. This is different with
non inline function...they are called, most likely by executing "call"
instruction (in x86 assembly)

Can you tell me their prototypes? just 2 or 3 of them? Quite likely
either they are explicitly inline function or decided by gcc to be
inlined because they are simple enough (thus "call" is considered a
bit expensive to do)

yes...if the function is inlined, there is no need to refer to the
function name (the symbol), right?
