Hi, All,

I have a question about iMeshP tag communication functions, including
iMeshP_pushTagsEnt, iMeshP_pushTags and etc. I think that the
specification is not clear. Should the involved parts provide the same
entities (entity copies) in calling those functions?

For example, the specification of iMeshP_pushTagsEnt is as follows:

 * Send tag information for specified entities, which must
 * already be shared.
 * The tag data is "pushed" from the
 * owner entities to all copies.

In some situation, mesh entity e0 is shared by part P0 and P1, and the
owner part is P0. In calling iMeshP_pushTagsEnt(..., entities,
entities_size,...), part P0 sends entity e0 (included in "entities" on P0)
to part P1, should part P1 also provide e0' (the entity copy on P1,
included in "entities" on P1) to receive the message?

Please correct me if you find any problems. Thanks,

Ting
