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 either 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, or CAPNG_AMBIENT. The values may be or'ed together to
perform the same operation on multiple sets. The last parameter, 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.
