NAME¶
capng_updatev - update the stored capabilities settings
SYNOPSIS¶
#include <cap-ng.h>
int capng_updatev(capng_act_t action, capng_type_t type, unsigned int capability, ...);
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 parameter, capability, is the capability define as given in linux/capability.h.
