请教OCIBindArrayOfStruct等函数的使用
请问：
OCIBindArrayOfStruct(OCIBind*bindpp,OCIError*errhp,,ub4pvskip,ub4indskip,ub4alskip,ub4rcskip)
OCIDefineArrayOfStruct(OCIDefine*defnp,OCIError*errhp,,ub4pvskip,ub4indskip,ub4alskip,ub4rcskip)
它们的参数是什么含义？如何与OCIBindByPos()和OCIDefineByPos()结合起来使用？
oracle是如何组织数据绑定的数据的？

能说说其中文含义嘛？如何与ocibindbypos结合起来使用？
