take


Description:

public static bool take (ref MiniObject olddata, MiniObject newdata)

Modifies a pointer to point to a new mini-object.

The modification is done atomically. This version is similar to replace except that it does not increase the refcount of newdata and thus takes ownership of newdata.

Either newdata and the value pointed to by olddata may be null.

Parameters:

olddata

pointer to a pointer to a mini-object to be replaced

newdata

pointer to new mini-object

Returns:

true if newdata was different from olddata
