CAPNG_HAVE_CAPABILITIES(3) Libcap-ng API CAPNG_HAVE_CAPABILITIES(3)
capng_have_capabilities, capng_have_permitted_capabilities - check for capabilities
#include <cap-ng.h>
capng_results_t capng_have_capabilities(capng_select_t set);
capng_results_t capng_have_permitted_capabilities(void);
capng_have_capabilities will check the selected internal
capabilities sets to see what the status is. The capabilities
sets must be previously setup with calls to
capng_get_caps_process, capng_get_caps_fd, or in some other way
setup. The options are CAPNG_SELECT_CAPS for the traditional
capabilities, CAPNG_SELECT_BOUNDS for the bounding set,
CAPNG_SELECT_BOTH if checking both are desired,
CAPNG_SELECT_AMBIENT if only checking the ambient capabilities,
or CAPNG_SELECT_ALL if testing all sets is desired. When
capabilities are checked, it will only look at the effective
capabilities.
If, however, the source of capabilities comes from a file, then
you may need to additionally check the permitted capabilities.
It's for this reason that capng_have_permitted_capabilities was
created. It takes no arguments because it simply checks the
permitted set.
This function will return one of the following four self
explanatory values: CAPNG_FAIL, CAPNG_NONE, CAPNG_PARTIAL,
CAPNG_FULL.
capng_get_caps_process(3), capng_get_caps_fd(3),
capng_have_capability(3), capabilities(7)
