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.

Parameters:

Returns:

The value returned by the wrapped acl_get_fd(3) system call.

 acl_t result = explain_acl_get_fd_on_error(fildes);
 if (result < 0)
 {
     ...cope with error
     ...no need to print error message
 }
