[MOAB-dev] Exchanging tags with no name

[Iulian Grindeanu]

Hello, 
The name of the tag gets "packed" in the communication packet that is sent. We should probably error out if a "no name" tag is sent. 
I would not use a no name tag, except a temporary tag in an application, and you always keep the tag handle itself (you can pass it around, store as a member data, etc) 
I don't think you can recover the "no name" tag handle in a separate portion of the code.

| Hello:


| I just tried calling exchange_tags on a tag with no name (when I
| created the tag I specified NULL as the first argument to
| tag_get_handle) and found that the tag exchange did not seem to work.
| After a lot of experimentation, I found that whether or not the tag
| had a name was the factor that determined whether the shared,
| not-owned entities successfully updated...


| Two questions:


| 1. Does exchange_tags require that the tag have a name specified?

| 2. Am I allowed to pass NULL as the name for tag_get_handle? Or must
| tags have names?


| Thank You

| Milad
