Function cuMemcpy

pub unsafe extern "C" fn cuMemcpy(
    dst: CUdeviceptr,
    src: CUdeviceptr,
    ByteCount: usize,
) -> CUresult

\brief Copies memory

Copies data between two pointers. \p dst and \p src are base pointers of the destination and source, respectively. \p ByteCount specifies the number of bytes to copy. Note that this function infers the type of the transfer (host to host, host to device, device to device, or device to host) from the pointer values. This function is only allowed in contexts which support unified addressing.

\param dst - Destination unified virtual address space pointer \param src - Source unified virtual address space pointer \param ByteCount - Size of memory copy in bytes
