CAPNG_PRINT_CAPS_NUMERIC(3)   Libcap-ng API   CAPNG_PRINT_CAPS_NUMERIC(3)

NAME         top

       capng_print_caps_numeric - print numeric values for capabilities
       set

SYNOPSIS         top

       #include <cap-ng.h>

       char *capng_print_caps_numeric(capng_print_t where, capng_select_t
       set);

DESCRIPTION         top

       capng_print_caps_numeric will create a numeric representation of
       the internal capabilities. The representation can be sent to
       either stdout or a buffer by passing CAPNG_PRINT_STDOUT or
       CAPNG_PRINT_BUFFER respectively for the where parameter. If the
       option was for a buffer, this function will malloc a buffer that
       the caller must free.

       The set parameter controls what is included in the representation.
       The legal options are CAPNG_SELECT_CAPS for the traditional
       capabilities, CAPNG_SELECT_BOUNDS for the bounding set,
       CAPNG_SELECT_BOTH if printing both is desired,
       CAPNG_SELECT_AMBIENT if only printing the ambient capabilities, or
       CAPNG_SELECT_ALL if printing all is desired.

RETURN VALUE         top

       If CAPNG_PRINT_BUFFER was selected for where, this will be the
       text buffer and NULL on failure. If CAPNG_PRINT_STDOUT was
       selected then this value will be NULL no matter what.
