NAME         top

       capng_updatev - update the stored capabilities settings

SYNOPSIS         top

       #include <cap-ng.h>

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

DESCRIPTION         top

       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_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.

RETURN VALUE         top

       This returns 0 on success and -1 on failure.
