Although inline functions are similar to macros (because the function code is expanded at the point of the call at compile time), inline functions are parsed by the compiler, whereas macros are expanded by the preprocessor. As a result, there are several important differences:...
Inline functions vs. macros See also Theinlinekeyword suggests that the compiler substitute the code within the function definition in place of each call to that function. In theory, using inline functions can make your program faster because they eliminate the overhead associated with function calls...
Expressions passed as arguments to inline functions are evaluated once. In some cases, expressions passed as arguments to macros can be evaluated more than once. Example The following example shows a macro that converts lowercase letters to uppercase: // inline_functions_macro.c #include <stdio....
Understanding Inline, __inline, And __forceinline Functions In C++ When To Use An Inline Function In C++? Advantages Of Inline Function In C++ Disadvantages Of Inline Function In C++ Why Not Use Macros Instead Of An Inline Function In C++?
// inline_keyword1.cpp // compile with: /c inline int max( int a , int b ) { if( a > b ) return a; return b; } A class's member functions can be declared inline either by using the inline keyword or by placing the function definition within the class definition.Example...
Inline functions take defined typed arguments where as macros can take any type as argument. Example syntax inline int swap(int *a, int *b); #define swap(a, b) Macros are expanded by the preprocessor before compilation takes place. Compiler will refer error messages in expanded macro to ...
It is a a preprocessor directive provided by C. It is declared by using the preprocessor directive #define before the actual statement. 2 Expressions passed as arguments to inline functions are evaluated once. In some cases, expressions passed as arguments to macros can be evaluated more than ...

It doesn't make much difference in this case since the calling conventions are fully compatible with functions that take one argument. The tag tells the library to cast it to a function pointer of the calling convention specified, so in this case, it will cast it to __fastcall. Since the...
