NAME

       capng_have_capabilities, capng_have_permitted_capabilities - check for capabilities

SYNOPSIS

       #include <cap-ng.h>

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

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.

RETURN VALUE

       This  function  will return one of the following four self explanatory values: CAPNG_FAIL,
       CAPNG_NONE, CAPNG_PARTIAL, CAPNG_FULL.
