CAPNG_GET_CAPS_FD(3)			  Libcap-ng API 		     CAPNG_GET_CAPS_FD(3)

NAME
       capng_get_caps_fd -

SYNOPSIS
       #include <cap-ng.h>

       int capng_get_caps_fd(int fd);

DESCRIPTION
       This  function  will read the file based capabilities stored in extended attributes of the
       file that the descriptor was opened against. The bounding set  is  not  included  in  file
       based  capabilities  operations.  Note  that this function will only work if compiled on a
       kernel that supports file based capabilities such as 2.6.26 and later. If the "magic"  bit
       is set, then all effect capability bits are set. Otherwise the bits are cleared.

RETURN VALUE
       This returns 0 on success and -1 on failure.
