Описание (Description)

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
       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.
