## ◆ H5T_conv_except_func_t

typedef H5T_conv_ret_t(* H5T_conv_except_func_t) (H5T_conv_except_t except_type, hid_t src_id, hid_t dst_id, void *src_buf, void *dst_buf, void *user_data)

Exception handler.

Parameters

  [in] | except_type | The kind of exception that occurred
  [in] | src_id | Source datatype identifier
  [in] | dst_id | Destination datatype identifier
  [in] | src_buf | Source data buffer
  [in,out] | dst_buf | Destination data buffer
  [in,out] | user_data | Callback context

Returns
  Valid callback function return values are H5T_CONV_ABORT, H5T_CONV_UNHANDLED and H5T_CONV_HANDLED.

If an exception like overflow happens during conversion, this function is called if it's registered through H5Pset_type_conv_cb().
