icetCopyState -- copy state machine of one context to another.
Contents
Bugs
The state is copied blindly. It is therefore possible to copy states that are invalid for a context's
communicator. For example, a display rank may not refer to a valid process id.

Description
The icetCopyState function replaces the state of dest with the current state of src. This function can
be used to quickly duplicate a context.
The IceTCommunicator object associated with dest is not changed (nor can it ever be). Consequently, the
following state values are not copied either, since they refer to process ids that are directly tied to
the IceTCommunicator object: ICET_RANK, ICET_NUM_PROCESSES, ICET_DATA_REPLICATION_GROUP,
ICET_DATA_REPLICATION_GROUP_SIZE, ICET_COMPOSITE_ORDER, and ICET_PROCESS_ORDERS. However, every other
state parameter is copied.
Errors
None.
Name
icetCopyState--copystatemachineofonecontexttoanother.
Notes
Behavior is undefined if dest or src has never been created or has already been destroyed.
