boost::uint32_t tia::DataPacket3Impl::getRequiredRawMemorySize	(	void *	mem,
		boost::uint32_t	bytes_available
	)		[virtual]

Get the required size (in bytes) to hold raw DataPacket stored in RAW memory. This function can be used to check, wether a memory region is able to hold a whole DataPacket by analyzing its header. If the RAW memory Region is too small to hold the DataPacket, 0 is returned.

Parameters:

[in]	mem	A pointer to the RAW memory region holding a DataPacket.
[in]	bytes_available	The memory size, the DataPacket is stored in.

Returns:

0 if the RAW memory region is too small to hold the DataPacket, otherwise the needed size of the raw memory region.

Todo:

Rewrite this mehtod as its size is now available inside the data packet.

Implements tia::DataPacket.
