动态数组实现, 包括了一个小例子.关键结构如下:

typedef struct Nameval Nameval



struct Nameval{

　　char　　*name

　　int　　value 　　

}



struct NVtab{

　　int nval 　　/* current number of values */

　　int max 　　/* allocated number of values */

　　Nameval *nameval 　　/* array of name-value pairs */

}nvtab



enum {NVINIT = 1, NVCROW = 2} -achieve dynamic array, including one small example. The key is structured as follows : typedef struct Nameval Nameval struct Nameval (char * name) int value struct (int NVtab nval / * current number of values * / int max / * allocated number of values * / Nameval nameval * / * array of name-value pairs * /) (NVINIT nvtab enum = 1, NVCROW = 2)
