捕获简单表填充异常

这是函数的一部分。文本是一个指针传递到函数。gfxxxCHAR * GETLIGAGEXETCIN PTR（const gfxxxCHAR *（*text））i，并在这里得到一个例外：如果（文本）！{NULL）{返回（GFXXXCHAR *）文本[语言]；} {{返回（GFXXXCHAR *）“”；//没有字符串？现在指针明显坏了。但是如何呢？它不是空的。需要一定范围内好吗？编译器有测试功能吗？我宁可排空格，也不例外。



      以下为原文

    This is part of a function. text is a pointer passes in to the function.
GFX_XCHAR *getLanguageStringPtr(const GFX_XCHAR *(*text))

I and getting an exception here:

if(text != NULL)
{
    return (GFX_XCHAR *)text[language];
}
else
{
    return (GFX_XCHAR *)""; // No string?
}

Now the pointer is obviously Bad.  But how?  It is Not Null.  does it need to be withing a certain range to be good?
doe the Compiler have a test function?  I would rather have to line blank then an exception.
