RE: [MI400] Space pointers

[Jim Langston <jlangston@xxxxxxxxxxx>]

I could think of a few uses.

1. I have a buffer I am using that, currently, is 1000 bytes.  I've used up
500 bytes so far.  I want to add an element that's 600 bytes.  Rather than
add 100 bytes to the end, re-allocate 600 bytes from byte 501.

2. I have a buffer of records that are 100 bytes each, and I have 10 so far,
for 1000 bytes.  I want to add a record into the middle.  Rather than add
the 100 bytes at the end and shift the records from 5 to 10 to the next
record, just add 100 bytes in the middle.

3. I want to delete a record in the middle as the above scenario.

I'm not saying I would do anything like this, but I could see how it would
be useful.

OK, I've used pointer-based languages for many years and I've never wanted
to allocate more memory in the middle of an allocation. Maybe that just
because I couldn't so my brain doesn't work that way, but why would you want
to do such a thing? Are you planning on having the allocation work like a
linked list where you're inserting a new element in the middle of the list?
