icetSetContext(3) IceT Reference icetSetContext(3)NAME
icetSetContext -- changes the current context.
Synopsis
#include <IceT.h>
void icetSetContext( IceTContext context );
Description
The icetSetContext function sets the IceT state machine to work with the context defined by context and the state associated with it. Fur-
ther calls to IceT functions will operate based on the state encapsulated in context. Changing the state of the context is a fast opera-
tion.
Errors
ICET_INVALID_VALUE
context is not valid.
Warnings
None.
Bugs
None known.
Notes
The behavior of icetSetContext is somewhat indeterminate if context is not valid. Usually, an ICET_INVALID_VALUE error will be raised, but
it is possible that the context will be set to some other context.

icetCopyState(3) IceT Reference icetCopyState(3)NAME
icetCopyState -- copy state machine of one context to another.
Synopsis
#include <IceT.h>
void icetCopyState( IceTContext dest,
const IceTContext src );
Description
The icetCopyState function replaces the state of dest with the current state of src. This function can be used to quickly duplicate a con-
text.
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.
Warnings
None.
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.
Notes
Behavior is undefined if dest or src has never been created or has already been destroyed.
