Embedded System
What is Embedded System?
An embedded system is a computer system with a
dedicated function within a larger mechanical or electrical
system. It is embedded in hardware and mechanical parts.
Embedded system contains processing cores that are
either microcontrollers or digital signal processors (DSP).

What is SDK?
SDK is an abbreviation of Software Development Kit,which
is also typical a set of software development tool for:
Creating Applications for Software Package
Software Framework
Operating System/Video Game Console
General Files
• API for Compilation
Common Tool
• Debugging Aids
IDE
Support Document
• Sample Code
Technical Notes
API specifies a set of functions or routines that accomplish
a specific task or allow to interact with a specific software
component. For example:
SYNOPSIS
DESCRIPTION
RETURNS
#include <math.h>
double sqrt(double X) / float sqrtf(float X);
sqrt computes the positive square root of the argument. ...
on success, the square root is returned. If X is real and positive...
DLL (Dynamic-link library) containing any combination of
code, data and resources is the concept of a shared library
in the Win OS. These libraries have file extensions such
as DLL,OCX, or DRV.
DLL provides a mechanism for shared code and data,
allowing a developer to share code or upgrade data without
re-compiling the interlinkage of applications.

The returned structure members Parameter, DefaultAuth is no sense, just keeping
compatible with OA200.
