1、动态加载模块并执行指南1文件我们将所有编译好的模块放在服务器上（譬如：102.168.0.204上的/modules/atm目录下）配置vxworks的nfs，使之创建nfs文件系统/modules并连接到服务器上参见相关文档2VxWorks镜像裁减保证需要增加如下组件：Developmenttools/loade/targetloaderDevelopmenttools/loade/targetunloaderDevelopmenttools/symboltable/symboltableDevelopmenttools
2、/symboltable/initializesymboltableNetworks/networkingprotocols/networkfilesystems/NFSclient1提供使用的函数wriLoadandRun1）wriLoadandRun的原形voidwriLoadandRun(char*filename,char*funcname){intfd;SYM_TYPE*pType;FUNCPTRfuncp;MODULE_IDmoduleId;charfn[100];hostAdd("Host","102.168

5、LOAD_COMMON_MATCH_ALL))==NULL){logMsg("loadModuleerrno:0x%x",errnoGet());close(fd);return;}/*closethefile*/close(fd);/*unmountthenfsthat
6、mountpreviously*/if(nfsUnmount(MOUNTENODE)==ERROR){logMsg("nfsUnmounterror:0x%x",errnoGet());}/*findtheentryfunction*/if(symFindByName(sysSymTbl,funcname,(char**)&funcp,pType)==ERROR){logMsg("sysFindByNameerrno=%x",errnoGet());}taskSpawn(funcname,100,0,10000,(
7、FUNCPTR)funcp,0,0,0,0,0,0,0,0,0,0);return;}1如何使用wriLoadandRun建议在usrAppInit.c添加如下代码：在usrAppInit（）加入voidusrAppInit(void){#ifdefUSER_APPL_INITUSER_APPL_INIT;/*forbackwardscompatibility*/wriLoadandRun（char*filename,char*funcname）；#endif/*addapplicationspecificcodehere
