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)
