Editing Inline function (section)

== Example ==
An <code>inline</code> function can be written in C or C++ like this:
<syntaxhighlight lang="c">
inline void swap(int *m, int *n)
{
    int tmp = *m;
    *m = *n;
    *n = tmp;
}
</syntaxhighlight>
Then, a statement such as the following:
<syntaxhighlight lang="c">
swap(&x, &y);
</syntaxhighlight>
may be translated into (if the compiler decides to do the inlining, which typically requires optimization to be enabled):
<syntaxhighlight lang="c">
int tmp = x;
x = y;
y = tmp;
</syntaxhighlight>
When implementing a sorting algorithm doing lots of swaps, this can increase the execution speed.
