I want to copy a string from ipxe to a specific region of memory in

I found there is prot_to_real/real_to_prot functions in iPXE source
code, but I didn't find any usage of this function. Should I use this
functions to copy string
from iPXE to real-mode region of memory? And would you please guide me
how should I do this type of copy?
Use real_to_user() to construct a userptr_t from your segment and
offset, then copy_to_user() to perform the copy.
