◆ vlMsgPackClear()

void vlMsgPackClear ( vl_msgpack * pack )

Clears the MessagePack DOM, resetting it for reuse.

This function resets the MessagePack DOM instance without deallocating memory. Previously allocated memory remains available for reuse, improving performance when repeatedly decoding into the same structure.

Parameters

pack	The MessagePack DOM instance to clear.

Here is the call graph for this function:

◆ vlMsgPackClone()

vl_msgpack * vlMsgPackClone	(	vl_msgpack *	src,
		vl_msgpack *	dest )

Clones the specified MessagePack DOM to another.

Clones the entirety of the src MessagePack to the dest MessagePack.

The 'src' DOM must be non-null and initialized. The 'dest' DOM may be null, but if it is not null it must be initialized.

If the 'dest' table pointer is null, a new DOM is created via vlMsgPackNew.

See also: vlMsgPackNew

Parameters

src	source DOM pointer
dest	destination DOM pointer

Returns: pointer to the MessagePack that was copied to or created.

Here is the call graph for this function:

◆ vlMsgPackDelete()
