pub const SHMMIN: i32 = 1;Expand description
SHMMNI, SHMMAX and SHMALL are default upper limits which can be modified by sysctl. The SHMMAX and SHMALL values have been chosen to be as large possible without facilitating scenarios where userspace causes overflows when adjusting the limits via operations of the form “retrieve current limit; add X; update limit”. It is therefore not advised to make SHMMAX and SHMALL any larger. These limits are suitable for both 32 and 64-bit systems. min shared seg size (bytes)
