WebThis allows the secondary arenas to keep growing almost indefinitely, only eventually failing when the kernel runs out of memory, or when the process runs out of address space.

Webmremap () changes the mapping between virtual addresses and memory pages. This can be used to implement a very efficient realloc (3) . In Linux, memory is divided into pages. A process has (one or) several linear virtual memory segments. Each virtual memory segment has one or more mappings to real memory pages (in the page table). rothman riddle

WebConsider the sbrk(2) system call. It does not actually allocate any more memory to the process.
