Constant SEMMNI

pub const SEMMNI: i32 = 32000; // 32_000i32

Available on crate feature dep_nc only.

SEMMNI, SEMMSL and SEMMNS are default values which can be modified by sysctl. The values has been chosen to be larger than necessary for any known configuration.

SEMOPM should not be increased beyond 1000, otherwise there is the risk that semop()/semtimedop() fails due to kernel memory fragmentation when allocating the sop array. <= IPCMNI max # of semaphore identifiers
