- If certain Debug Agent Library instance has to save some private data in the stack,

- the caller needs to wrap up all rest of logic after InitializeDebugAgent() into one
- function and pass it into InitializeDebugAgent(). InitializeDebugAgent() is
- responsible to invoke the passing-in function at the end of InitializeDebugAgent().
-
- If the parameter Function is not NULL, Debug Agent Libary instance will invoke it by
- passing in the Context to be its parameter.
-
- If Function() is NULL, Debug Agent Library instance will return after setup debug
- environment.
-
- @param[in] InitFlag Init flag is used to decide the initialize process.
- @param[in] Context Context needed according to InitFlag; it was optional.
- @param[in] Function Continue function called by debug agent library; it was
