# Function volatile_set_memory

Source

    pub unsafe fn volatile_set_memory<T>(dst: *mut T, val: u8, count: usize)

🔬This is a nightly-only experimental API. (`core_intrinsics`)
Expand description

Equivalent to the appropriate `llvm.memset.p0i8.*` intrinsic, with a size of `count * size_of::<T>()` and an alignment of `align_of::<T>()`.

This intrinsic does not have a stable counterpart.

## §Safety

The safety requirements are consistent with `write_bytes` while the write behavior is volatile, which means it will not be optimized out unless `_count` or `size_of::<T>()` is equal to zero.
