Subject: Map list of strings into memory
I would like to map file created with
find / >the_file
(text file, each line one entry) into memory with golang and then iterate
func Mmap(fd int, offset int64, length int, prot int, flags int) (data
which returns byte slice, now, to read a line I plan to reach byte by byte.
Is there something if I would replace newlines in the file with zero bytes?
Thanks

Why don't you use ioutil/ReadFile?
Or just open the file with and read line by line with bufio/ReadLine?
