Typedef Documentation

void(* QSE_decode)(void *context, const LSF_record *record, void *prm)

Callback signature for user provided event handler.

Parameters:

	context	The update context
	prm	User provided parameter, used to dynamically select expansion/decoding options.
	record	The event record to expand

void(* QSE_updateAtContribution)(void *context, const LSF_contribution *contribution)

Updates the contribution context based on the contribution.

Parameters:

	context	The QSE update context
	contribution	The contribution

void(* QSE_updateAtDatagram)(void *context, const LSF_datagram *datagram)

Updates the run oriented information in the event context using the information from the event datagram.

Parameters:

	context	The update context
	datagram	The event datagram

int(* QSE_updateAtRecord)(void *context, const LSF_record *record)

Updates the context based on the record.

Returns:

Whether this record contains an event

Parameters:

	context	The update context
	record	The record

void *(* QSE_updateConstruct)(void *context, void *prm)

Constructs (initializes) the structure needed for updating the event handling context.

Parameters:

	context	The context to initialize. If passed in as NULL, then a context will be alllocated.
	prm	An optional parameter used to tailor the context. In most cases, this will be the same value as passed to the sizeof routine

void(* QSE_updateDestruct)(void *context)

Deconstructs (initializes) the update context.

Parameters:

	context	The context to initialize
	prm	An optional parameter used to tailor the context. In most cases, this will be the same value as passed to the sizeof routine

int(* QSE_updateSizeof)(void *prm)

Returns the size, in bytes, of the structure needed for updating all the context associated with the event handling.

Returns:

The size, in bytes, of the structure needed for updating all the context associated with event handling.

Parameters:

prm

An optional parameter used to tailor the style of updating In most cases, this will be the same value as passed to the construct routine.
