in MessageBuffer. - Status

earlier in this chapter, for more information.
Description | |
The MCErrMsg intrinsic gives you the message that corresponds
to the status info value you received in a previous intrinsic call.
The MCErrMsg intrinsic obtains only local information; it will
not return messages generated on the remote side. MCErrMsg can be called from any conversation state, and
it does not change the state of the conversation. Status Info Values | |
