Hi
Ok, I know BSD ppl may not like it, but anyway I have few questions I
think some of you know the answers.
Sys V ipc (at least the calls related to shared mem and messages queues)
seems to _not_ be implemented as system calls.
Indeed, ktrace/kdump wont records them as system calls (even if the
manpage for shmat is in section 2 ;=)
I experienced the following:
- msgrcv() with IPC_NOWAIT return EWOULDBLOCK instead of ENOMSG (Linux
and Sys V)
- a process can have no more than 8 shared mem segments
(how can I change this ?)
Is the above the expected behaviors ?
Can one confirm/infirm ?
Tia
Meir
