[转载]使用masm32开发基于SPI的应用层SNIFFER
文章作者：czy信息来源：[url]www.cnwill.com[/url]
安装程序spi.asm
DLL:spidll.asm
DLL生成后放在C盘下改名为rood.dll
编绎参数:
ml /c /coff spidll.asm
link /DLL /DEF:spidll.def /SUBSYSTEM:windows spidll.obj
ml /c /coff spi.asm
link /subsystem:CONSOLE spi.obj
dll的def文件
EXPORTS WSPStartup
在2KPRO下测试很稳定,效率要比C的高不少哟,俺可是一个指令一个指令的
优化过..

;the logfile is c:\snifferpass.txt and format like this:
