How Do I Make A Function Inline?

You can ask the compiler to inline a function by using the inline specifier (see Inline Specifier) or #pragma inline. This is only a suggestion to the compiler and cannot always be obeyed. Do not confuse this specifier/pragma with the intrinsic pragma⁽¹⁾ (see The #pragma Intrinsic Directive), which is for functions that have no corresponding source code and which will be specifically expanded by the code generator during compilation.
