kill_dependency - cppreference.com (original) (raw)
| | | | | -------------------------- | | ----------- | | A kill_dependency( A y ); | | (since C11) |
Informs the compiler that the dependency tree started by an memory_order_consume atomic load operation does not extend past the return value of kill_dependency; that is, the argument does not carry a dependency into the return value.
The function is implemented as a macro. A is the type of y.
[edit] Parameters
| y | - | the expression whose return value is to be removed from a dependency tree |
|---|
[edit] Return value
Returns y, no longer a part of a dependency tree.
