I can use "sysctl kern.sysv.shmmax" or "ipcs -M" to get the integer
(4194304). But they are both command line tools. It is not
convenient to call it inside the problem.
I also have tried to use the sysctlbyname system call: sysctlbyname
("kern.sysv.shmmax", &shmmax, &len, NULL, NULL). Although this call
return 0, the shmmax variable does not hold the correct value.
By the way, my system is Leopard.
Can anybody tell me an appropriate way? Thank you in advance!
'sysctl(1)' just uses 'sysctl(2)'. Check the man page ("man 2
sysctl") and the source for 'sysctl(1)' available on Apple's Darwin
website (the 'system_cmds-431' project, for 10.5).
