data exchange (DDE) callback function receives the XTYP_ERROR transaction when
a critical error occurs.

is not associated with a conversation.

Memory is
low; advise, poke, or execute data may be lost, or the system may fail. |

Remarks
An
application cannot block this transaction type; the CBR_BLOCK return code is
ignored. The DDEML attempts to free memory by removing noncritical resources.
An application that has blocked conversations should unblock them.
