DDCVersion()

const DDCVersionT DDCVersion	(	2	,
		2	,
		8
	)

returns current DDC Version as a DDCVersionT (caveat: not useable in global initializers!)

Minimum index version this DDC can read

Minimum DDC version which can read files written by us

ddc_parse_format_version()

void ddc_parse_format_version	(	const char *	s,
		DDCVersionT &	version,
		DDCVersionT &	version_min
	)

parse a file version string of one of the following forms:

• "... Format FORMAT_VERSION ... min-compat FORMAT_VERSION_MIN ..."
• "... Format FORMAT_VERSION ..."
• "... Version FORMAT_VERSION ... min-compat FORMAT_VERSION_MIN ..."
• "... Version FORMAT_VERSION ..."

In the second and fourth cases, FORMAT_VERSION_MIN is set to FORMAT_VERSION. If parse fails, version and version_min are set to 0 (zero).

Parameters

version	on completion contains FORMAT_VERSION parsed from s, or 0
version_min	on completion contains FORMAT_VERSION_MIN parsed from s, or 0

Here is the caller graph for this function:

ddc_format_version_check()

void ddc_format_version_check	(	const char *	s,
		const char *	label = NULL
	)

check a stored format version string s for compatibility with the running ddc; otherwise throws a CExpc(errLogic). label is used for the exception message; it defaults to s.
