16       capng_updatev will update  the  internal  posix  capabilities  settings
17       based  on  the  options  passed  to  it.  The  action  should be either
18       CAPNG_DROP to set the capability bit to 0,  or  CAPNG_ADD  to  set  the
19       capability  bit  to 1. The operation is performed on the capability set
20       specified in the  type  parameter.  The  values  are:  CAPNG_EFFECTIVE,
21       CAPNG_PERMITTED,  CAPNG_INHERITABLE, CAPNG_BOUNDING_SET, or CAPNG_AMBI‐
22       ENT. The values may be or'ed together to perform the same operation  on
23       multiple  sets. The last paramter, capability, is the capability define
24       as given in linux/capability.h.

26       This function differs from capng_update in that you may pass a list  of
