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

NAME         top

       capng_get_caps_fd - read file-based capabilities from extended
       attributes

SYNOPSIS         top

       #include <cap-ng.h>

       int capng_get_caps_fd(int fd);

DESCRIPTION         top

       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         top

       This returns 0 on success and -1 on failure.
