Member Function Documentation

deserialize()

bool Clone_Desc_State::deserialize	(	const byte *	desc_state,
		uint	desc_len
	)

Deserialize the descriptor.

Parameters

[in]	desc_state	serialized descriptor
[in]	desc_len	descriptor length

Returns

true, if successful.

init_header()

void Clone_Desc_State::init_header

(

uint

version

)

Initialize header.

Parameters
