Using memset in the CUDA core

Question

This seems like an obvious problem, but Google is not causing anything interesting. Is it legal to use memsetCUDA in the kernel, for example:

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

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

Answer 1

Yes, as described in Appendix B of the Programming Guide , memsetas well as memcpy, mallocand free(the latter two only functions Compute> = 2.0) are supported in device code.
