__forceinline

 Similar to the __inline storage-class modifier, the __forceinline
 storage-class modifier marks a function for inline expansion.
 However, using __forceinline on a function definition and prototype
 tells the compiler that it must substitute the code within the
 function definition for every call to that function.  (With
 __inline, such substitution occurs at the discretion of the
 compiler.)

 Syntax:

      __forceinline [type] function_definition
