Can I create a circular buffer on Linux? (current code segfaults)

QUESTION

Can I create a circular buffer on Linux? (current code segfaults)

Asked 2022-Mar-22 at 17:47

Inspired by this example for Windows. In short, they create a file handle (with CreateFileMapping) then create 2 different pointers to the same memory (MapViewOfFileEx or MapViewOfFile3)

So I tried to do the same thing with shm_open, ftruncate and mmap. I used mmap a few times in the past for memory and files but I never mixed it with shm_open or used shm_open.

My code fails on the second mmap with a segfault. I tried doing a syscall directly on both mmaps and it still segfaults :( How do I do this properly? The idea is I can do memcpy(p+len-10, src, 20) and have the first 10bytes of src be at the end of the memory and last 10 written to the start (hence circular)

...

You do not need to call mmap again to gen new pointer. (You even must not to do it.) Just increment it.

The pointer p2 will not point to the address just after the memory block allocated.

Support

refterm is designed to support several features, just to ensure that no shortcuts have been taken in the design of the renderer. As such, refterm supports:. These features are not designed to be comprehensive, since this is only meant to be a reference renderer, not a complete terminal.
