where to find this declaration

Question

in a challenge in c there is a question:
Are the following declarations the same?
char far *far *scr;
char far far** scr;

but I didn't see any declaration like those
what is its name?
how to make it (if it is possible)?

thanks for help

Answer 1

it's outdated, its called far pointers, it's usable but you will definitely find no use for it

Answer 2

wow ... thanks for information ... should it still in challenges?
