This action can be used to retrieve the size of a buffer, in bytes. You supply the unique buffer ID value as returned by the action Create Buffer and then give a target variable to return the size value to. The target variable can be flagged as being a temporary local variable, in which case it will be created for you and removed from memory again at the end of the current action script or event.
Argument Description Buffer The buffer index (stored in a variable) Target The target variable to hold the returned value
The above action block code gets the size of the buffer and then uses that value to set the read/write position to the end of the currently stored data.
