嵌入式应用系统邮件发送模块的C语言编程

文章阐述用C语言设计实现嵌入式应用系统邮件发送模块的技术要点及关键步骤,包括嵌入式系统对邮件发送功能需求的简要分析、实现邮件发送功能的基本原理、C语言设计实现的具体方法等.最后通过一个小型CGI程序演示其功能,实现基于Web的邮件发送.通过在X86平台和ARM平台分别实验,都达到预期效果.该邮件发送模块在Linux平台用GNU工具链作开发,整个程序小巧简洁、功能独立,可在任何嵌入式应用系统中使用,很有实用价值.

Programming Mail Sending Module in C for Embedded Application System

This paper describes the technical issues and key steps for designing and implementing mail sending module for embedded application systems in C,including a brief analysis of requirements for mail sending function,the basic principles of implementing it,the methods of design and implementing in C,etc.A tiny CGI program is given to show the function of realizing Web based mail sending.By testing in X86 and ARM platforms,the expected results are both achieved.The mail sending module is developed with GNU tool chain on Linux.The entire program is small and simple,independent of functions,and can be used in any embedded application system hence has much of practical value.
