# kill_dependency

Defined in header `<stdatomic.h>` |  |
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`.

### Parameters

y | - | the expression whose return value is to be removed from a dependency tree

### Return value

Returns `y`, no longer a part of a dependency tree.
