Using memset in a CUDA kernel

Question

This seems like an obvious issue, but Google turns up nothing interesting. Is it legal to use memset in a CUDA kernel such as:

__device__ void myKernel()
{
    int array[10];
    memset(array, 0, sizeof(array));
    // ...etc...
}

(I know int array[10] = {0}; is probably better, but this is just an example of a more complicated case.)

Answer 1

是的，如编程手册附录B中所述 ，设备代码支持memset以及memcpy ， malloc和free （仅后者在Compute Capacity> = 2.0设备上提供）。
