Hello list,

Why not RFMEM? Imho on POSIX-fork(), the child shares the address-space with the parents.
It is not that I really care myself, #include <lib9.h> fixes a lot of things,;)
,but I fear programmes which rely on that may not work. Is there a specific reason
fork.c:fork() does not fork with RFMEM?
Mfg, Sascha
rfork (2):
``RFMEM --- If set, the child and the parent will share data and bss
segments. Otherwise, the child inherits a copy of those segments. Other
segment types, in particular stack segments, will be unaffected. May be
set only with RFPROC.''
POSIX-fork() copies data and bss segmets, child process doesn't share
data with it's parent. There are POSIX-threads, SYSV-IPC to share memory.
