cuda::is_aligned

[[nodiscard]] __host__ __device__ inline
bool is_aligned(const void* ptr, size_t alignment) noexcept

The function determines if a pointer is aligned to a specific alignment.

Parameters

• ptr: The pointer.

• alignment: The alignment.

Return value

• true if the pointer is aligned to the specified alignment, false otherwise.

Constraints

• alignment must be a power of two.

Example

#include <cuda/memory>

__global__ void kernel(const void* ptr) {
    assert(cuda::is_aligned(ptr, 16));
}

int main() {
    void* ptr;
    cudaMalloc(&ptr, 100 * sizeof(int));
    kernel<<<1, 1>>>(ptr);
    cudaDeviceSynchronize();
    return 0;
}
