CapabilityMask

Struct CapabilityMask 

Source
pub struct CapabilityMask(/* private fields */);
Expand description

Bitmask des capabilities.

Représentation interne u64 : le bit i est positionné ssi la Capability de valeur numérique i est dans le masque. Les Linux v3 capabilities (kernel ≥ 2.6.25) utilisent 64 bits côté kernel, exposés par l’ABI capget/capset sous forme de deux mots u32 (bits 0-31 puis bits 32-63) ; la conversion est réalisée par les helpers du wrapper air-sys-syscall.
