I'm trying to understand the reason behind the introduction of segbrk(2). I cannot find a use case in the codebase.
The manual <http://man.cat-v.org/plan_9/2/segbrk>page states that: The segbrk system call may go away or be re-implemented to give more general segment control, sub- suming the functions of brk(2) <http://man.cat-v.org/plan_9/2/brk>, segflush(2) <http://man.cat-v.org/plan_9/2/segflush> and segfree insegattach(2) <http://man.cat-v.org/plan_9/2/segattach>. But given the manpage itself is pretty cryptic, I wonder if it's outdated. Or if it is actually deprecated. Do you know any paper that can explain its design and intent? Giacomo
