CAPNG_UPDATEV(3)		 Libcap-ng API		      CAPNG_UPDATEV(3)

       capng_updatev - update the stored capabilities settings

       #include <cap-ng.h>

       int  capng_updatev(capng_act_t action, capng_type_t type,      unsigned
       int capability, ...);

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

       This  function differs from capng_update in that you may pass a list of
       capabilities. This list must be terminated with a -1 value.

       This returns 0 on success and -1 on failure.
