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
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.
This returns 0 on success and -1 on failure.
