XTYP_ERROR

XTYP_ERROR 
 

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

Parameters

uFmt

Not used.

hconv

Handle to the conversation associated with the error. This parameter is NULL if the error is not associated with a conversation.

hsz1

Not used.

hsz2

Not used.

hdata

Not used.

dwData1

Specifies the error code in the low-order word. Currently, only the following error code is supported:

Error Code	Description
DMLERR_LOW_MEMORY	Memory is low; advise, poke, or execute data may be lost, or the system may fail.

dwData2

Not used.

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.
