how to assign a “const void*” to a “const uint64_t*” in cuda c?

I want to assign "const void*" to a "const uint64_t*" in cuda c.

I have done like this,

Code:

void func(const void *buffer)
    {
      const uint64_t *words = buffer;
    }

but i'm getting an error like this,

Quote:

error: a value of type "const void *" cannot be used to initialize an entity of type "const uint64_t*"

can anyone help me in solving this problem?

typecast is the name of the magic:

Code:

const uint64_t *words = (uint64_t *)buffer;

I think you need the const in the cast as well:

Code:

const uint64_t *words = (const uint64_t *)buffer;
