Function Documentation

choose_desc_version()

uint choose_desc_version

(

const byte *

ref_loc

)

Choose lowest descriptor version between reference locator and currently supported version.

Parameters

[in]

ref_loc

reference locator

Returns

chosen version

clone_validate_locator()

bool clone_validate_locator	(	const byte *	desc_loc,
		uint	desc_len
	)

Check if clone locator is valid.

Parameters

[in]	desc_loc	serialized descriptor
[in]	desc_len	descriptor length
