## __TBB_LONG_LONG

#define __TBB_LONG_LONG long long

Definition at line 39 of file atomic.h.

## __TBB_MINUS_ONE

#define __TBB_MINUS_ONE | ( |  | T | ) | (T(T(0)-T(1)))

Additive inverse of 1 for type T.

Various compilers issue various warnings if -1 is used with various integer types. The baroque expression below avoids all the warnings (we hope).
