convert_to_40()

uint32_t offline_eformat::old::convert_to_40	(	const uint32_t *	src,
		uint32_t *	dest,
		uint32_t	max,
		eformat::CheckSum	event_checksum = eformat::NO_CHECKSUM,
		eformat::CheckSum	rob_checksum = eformat::NO_CHECKSUM
	)

Converts a full event fragment or a ROS fragment, from some format to v4.0 format, using the space of contiguous memory storage area given.

If the event given is already on the current format, no conversion takes place.

Parameters

src	A pointer to the first word of the event, lying in a contiguous area of memory.
dest	The destination area of memory, preallocated
max	The maximum number of words that fit in the preallocated memory area "dest".
event_checksum	What type of checksum to deploy for full events
rob_checksum	What type of checksum to deploy for rob fragments

Returns

A counter, for the number of words copied from the source to the destination. If that number is zero, something wrong happened.
