ARGUMENTS

nq_context

A message enqueue context created with PMDF_start_message_envelope.

DESCRIPTION

Generally, expansion of aliases should never be inhibited. However, there is at least one situation where alias expansion must be inhibited. That situation arises when a message being dequeued needs to be re-enqueued to the same channel with a subset of its envelope recipient list. That is done by enqueuing a new message, inhibiting alias expansion, specifying only the envelope addresses of the desired subset, ending the envelope, and then copying the message content verbatim with PMDF_copy_message.
Return Values
PMDF__OK Normal, successful completion.
