) }
MPI_TYPE_DUP is
a type constructor
which duplicates the existing type
with associated key values.
For each key value, the respective copy
callback function determines the attribute value associated with this
key in the new communicator; one particular action that a copy
callback may take is to delete the attribute from the new datatype.
Returns in newtype a new datatype with exactly the same
properties as type and any copied cached
information, see Section Datatypes
on page Datatypes
.
The new datatype has identical
upper bound and lower bound and yields the same net result when fully
decoded with the functions in Section Decoding a Datatype
.
The
newtype has the same committed state as the old
type.
