Синопсис (Synopsis)

       capng_results_t capng_have_capabilities(capng_select_t set);
       capng_results_t capng_have_permitted_capabilities(void);

Описание (Description)

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.
