[9fans] segbrk(2) vs friends

[Giacomo Tesio]

I'm trying to understand the reason behind the introduction of segbrk(2).

I cannot find a use case in the codebase.

The manual 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) ,
segflush(2)  and segfree
insegattach(2) .


But given the manpage itself is pretty cryptic, I wonder if it's outdated.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?
