Functions
uint32_t	convert_source (uint32_t old_id)
uint32_t	convert (const uint32_t *src, uint32_t *dest, uint32_t max)

Detailed Description

Includes classes and non-member methods that allows provisional reading from event format v2.4. The main purpose of this functionality is conversion from the old to the new event format.

Function Documentation

convert()

uint32_t eformat::old::convert	(	const uint32_t *	src,
		uint32_t *	dest,
		uint32_t	max
	)

Converts a full event fragment, from the old to new format, using the space of contiguous memory storage area given. If the event given is already on v3.0 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".

Returns

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