Function Documentation

int HCI_CallNormal (  HC_Sequence_t *    sequence,
long    nodenum,
void *    userdata
) 
 

Call the normal function for the given node.

Parameters:
sequence  Sequence object.
nodenum  Node number of the normal function.
userdata  User-defined data.
Returns:
An error code.

int HCI_CallPolicy (  HC_Sequence_t *    sequence,
long    nodenum,
void *    userdata,
HC_PolicyEvent_t    event,
long    policy_data
) 
 

Call the policy function for the given node.

Parameters:
sequence  Sequence object.
nodenum  Node number of the policy function.
userdata  User-defined data.
event  The event that has occured.
policy_data  The policy-specific data.
Returns:
An error code.

int HCI_CallRollback (  HC_Sequence_t *    sequence,
long    nodenum,
void *    userdata,
unsigned long    checkpoint
) 
 

Call the rollback function for the given node.

Parameters:
sequence  Sequence object.
nodenum  Node number of the rollback function.
userdata  User-defined data.
checkpoint  The checkpoint value last cleared in the normal function.
Returns:
An error code.

long HCI_PopNode (  HC_Sequence_t *    sequence ) 
 

Pops a node from the stack.

Parameters:
sequence  The sequence object.
Returns:
The node popped from the stack or an error code (<0)

int HCI_PushNode (  HC_Sequence_t *    sequence,
long    node
) 
 

Pushes a node onto the stack.

Parameters:
sequence  The sequence object.
node  The node to be pushed.
Returns:
An error code.
