noinline
Microsoft Specific
__declspec(noinline)
tells the compiler to never inline a particular member function (function in a class).
It may be worthwhile to not inline a function if it is small and not critical to the performance of your code. That is, if the function is small and not likely to be called often, such as a function that handles an error condition.
Keep in mind that if a function is marked noinline
, the calling function will be smaller and thus, itself a candidate for compiler inlining.
class X {
__declspec(noinline) int mbrfunc() {
return 0;
} // will not inline
};
