如果是null则抛出NullPointerException异常。 七、未经检查的转换(Unchecked Conversion) 未检查的转换是指多类型数组,进行转换。会在编译时报SuppressWarnings。 未检查的转换用于使遗留代码(在引入泛型之前)与经过转换以使用泛型(我们称为泛化的过程)的库之间实现平滑的互操作。在这种情况下(最值得注意的是,中的Collectio...
String pointer (same as buffer) will be returned. When passed a non-valid radix argument, function will return NULL and set errno to EINVAL. Portability considerations This is a non-standard function. Even though the prototype given is commonly used by compilers on other platforms, there is no...
