Function Documentation

static unsigned long long int get_event_time

(

const EBF_gem *

gem

)

[static]

Gets the absolute (WCT) time of the event.

Returns:

The absolute time of the event

Parameters:

gem

The GEM contribution for this event

static int grb_process	(	GRBP_server *	server,
		EDS_fwIxb *	ixb,
		GRB_msgHdr *	msg_hdr,
		int	len32
	)			[static]

This is the client side GRBP processing routine. It's job is to decide whether this event should be nominated as a GRB candidate and, if so, to package its parameters for the client side to analyze.

Return values:

	<	0, the message will not fit. The caller is expected to recall this routine with enough memory (the absolute value of this return value is number of 32-bit words needed.
	>	0, the number of 32-bit words committed to the message
	==0,event	is not a candidate.

Parameters:

	server	The server handle
	ixb	The information exchange block for the event
	msg_hdr	Pointer to the header of the message to be filled out. It is assumed that the memory for the processing specific part of the message (here GRBP_msgBdy) immediately follows this header
	len32	The number of 32-bit words available for the message

This is exported only via the GRBP_serverServicesGet routine. It is called back once per event.

const GRB_epuServices* GRBP_serverServicesGet	(	GRBP_server *	server,
		const GRBP_DB_serverSchema *	cfg
	)

Standard GRB algorithm construct service.

Returns:

The EPU service vector

int GRBP_serverSizeof

(

const GRBP_DB_serverSchema *

)

Returns the size, in bytes, needed for the specified server configuration.

Returns:

The size, in bytes, needed for the specified server configuration

Parameters:

cfg

The server configuration

static void __inline prjList_init

(

TFC_prjList

lists[2][16]

)

[static]

Initialize the by-layer linked list. Note that the 16 is NOT the number of towers, but is the number of layers that can be considered either the beginning or ending of a track. Since tracks must have at least two layers, this is 18 - 2.

Parameters:

lists
