DESCRIPTION

These functions work with the following data types:

cap_value_t

identifies a capability, such as CAP_CHOWN.

cap_flag_t

identifies one of the three flags associated with a capability (i.e., it identifies one of the three capability sets). Valid values for this type are CAP_EFFECTIVE, CAP_INHERITABLE or CAP_PERMITTED.

cap_flag_value_t

identifies the setting of a particular capability flag (i.e, the value of a capability in a set). Valid values for this type are CAP_CLEAR(0) or CAP_SET(1).
