NAME         top

       capng_apply_caps_fd -

SYNOPSIS         top

       #include <cap-ng.h>

       int capng_apply_caps_fd(int fd);

DESCRIPTION         top

       This function will write the file based capabilities to the
       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 2.6.2 6 and later.

RETURN VALUE         top

       This returns 0 on success, -1 if something besides a regular file
       is passed, and -2 if a non-root namespace id is being used for
       rootid.
