Subject:	get alias "real" name

I was wondering if the the correct way to get the PV aliased name is to look at the .NAME field of its alias.

If I do

Ø pvget myalias.NAME

I should get the “real” PV name which the alias point to.

However this start to not be true if the length of the “real” PV name is > 39 chars ( <= 60 )

since the .NAME filed value is truncated to 39 chars (maybe some limitation on DBR_STRING ?)

Best
