5.17 Low-Level Parameter Implementation
Earlier, when discussing HLA's high-level parameter passing mechanism, there were several questions concerning parameters. Some important questions are:
Where is the data coming from?
What mechanism do you use to pass and return data?
How much data are you passing?
In this section we will take another look at the two most common parameter-passing mechanisms: pass by value and pass by reference. We will discuss three popular places to pass parameters by reference or by value: in the registers, on the stack, and in the code stream. The amount of parameter data has a direct bearing on where and how to pass it. The following sections take up these issues.
