struct GenInfo {
uint64_t (*next)(struct GenInfo * const);
enum GeneratorType type;
union {
struct GenInfo_Constant constant;
struct GenInfo_Counter counter;
struct GenInfo_Discrete discrete;
struct GenInfo_Exponential exponential;
struct GenInfo_File file;
struct GenInfo_Histogram histogram;
struct GenInfo_HotSet hotset;
struct GenInfo_Zipfian zipfian;
struct GenInfo_Latest latest;
struct GenInfo_Uniform uniform;
} gen;
};
该结构体内的第一行： uint64_t (*next)(struct GenInfo * const); 这一行表示的是什么？
是不是指向下一个该结构体的指针呢？
谢谢。
