## Detailed Description

The namespace tbb contains all components of the library.

## Enumeration Type Documentation

enum tbb::memory_semantics

Specifies memory semantics.

Enumerator
full_fence | Sequential consistency.
acquire | Acquire.
release | Release.
relaxed | No ordering.

## Function Documentation

int __TBB_EXPORTED_FUNC tbb::TBB_runtime_interface_version | ( | ) |  |

The function returns the interface version of the TBB shared library being used.

The version it returns is determined at runtime, not at compile/link time. So it can be different than the value of TBB_INTERFACE_VERSION obtained at compile time.
