#define LFDS611_INLINE [compiler inline directive]
No return value.
The atomic instructions used by liblfds in the end always come down to a single machine instruction. Part of the reason for using lock-free data structures is performance. As such, it is important to indicate to the compiler that it should if at all possible avoid the overhead of a function call every time one of the atomic instructions is called. To achieve this, compilers provide a keyword which permits the code author to indicate that a given function should be inlined. This macro is the mechanism by which the compiler specific keyword for function inlining is provided to liblfds.
On Windows, with the Microsoft C compiler, there exists the keyword __forceinline.
As such, the implementation of LFDS611_INLINE on Windows with the Microsoft C compiler looks like this;
#define LFDS611_INLINE __forceinline
With GCC, there exists the keyword inline.
As such, the implementation of LFDS611_INLINE on GCC looks like this;
#define LFDS611_INLINE inline
