acl_t explain_acl_get_fd_on_error(int fildes);
DESCRIPTION¶The explain_acl_get_fd_or_die function is used to call the acl_get_fd(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_acl_get_fd(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_acl_get_fd_on_error function is used to call the acl_get_fd(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_acl_get_fd(3) function, but still returns to the caller.
- The fildes, exactly as to be passed to the acl_get_fd(3) system call.
RETURN VALUE¶The explain_acl_get_fd_or_die function only returns on success, see acl_get_fd(3) for more information. On failure, prints an explanation and exits, it does not return.
