NAME
copy_to_phys - General: Copies data from a virtual address to a physical address

void copy_to_phys(
vm_offset_t virt_src,
vm_offset_t phys_dest,

ARGUMENTS
Specifies the virtual address of the data to be copied. Specifies the physical address to copy the data to. Specifies the number of bytes
