Detailed Description

PBC application-level command handlers.

    CVS $Id: PBC_command.c,v 1.11 2011/03/29 23:14:58 apw Exp $
    

Application-level handlers for the PBC boot commands. These handlers simply forward the commands to a target node.

Function Documentation

unsigned int pbc_forward_cmd	(	const ITC_QueueItem *	qitem_p,
		void *	pkt_p,
		unsigned int	len,
		int *	fwd_p
	)			[static]

Common routine to forward PBC commands to other nodes.

This function looks at a PBC (boot) telecommand packet and determines if it should be forwarded to another node (CPU). It assumes that the ID of the target node is located in the same place within all PBC telecommand packets.

Parameters:

	qitem_p	Pointer to queue item.
	pkt_p	Pointer to telecommand packet.
	len	Length of telecommand packet, in bytes.
	fwd_p	Location to store pkt disposition (nonzero=>forwarded).

Returns:

MSG code.

unsigned int PBC_LBTBAD	(	void *	prm,
		const struct _ITC_QueueItem *	qitem,
		void *	pay,
		unsigned int	len
	)

Handle the invalid Boot command (for testing purposes).

Parameters:

	prm	Pointer to a context parameter (unused).
	qitem	Pointer to queue item (unused).
	pay	Pointer to command payload.
	len	Length of the command payload, in bytes.

Returns:

MSG code.
