Inlining (C++ and PHP Cross Reference Guide)

By Mike Prestwood

C++ versus PHP: A side by side comparison between C++ and PHP.

Language Details

Language Details is kind of a catch all for stuff that didn't make it into language basics nor any other category.

Inlining

[Other Languages]

General Info: Inline Routines

Instead of calling a routine, you move the code from the routine itself and expand it in place of the call. In addition to manual inlining, some languages support automatic inlining where the compiler or some other pre-compiler decides when to inline a code routine. Also, some languages allow for developer defined inlining where the developer can suggest and/or force the inlining of a code routine. Inlining can optimize your code for speed by saving a call and return, and parameter management.

Languages Focus

Does it support inlining? If so, does it support developer defined inlining? Does it support automatic inlining? Both?

C++: inline

In both Visual C++ and C++Builder, use the inline (standard C++) or __inline (standard C and C++) keywords to suggest to the compiler to inline a routine.

Microsoft also offers __forceinline and _inline, Microsoft specific specifiers where __forceinline is a stronger suggestion but still does not always mean the routine will be inlined as well as _inline for backward compatibility.

Syntax Example:

inline int add(int p1, int p2) {
  int result;

  result = p1 + p2;
  return result;
};
