_m_usmart_nametab的结构体如下
//函数名列表 struct _m_usmart_nametab{void* func; //函数指针const u8* name; //函数名(查找串) };一开始一直不明白，为什么下边的只有两个参数，而上边的确有那么多，难道不是一一对应？
其实上边的是一个table表，就像 u8 table[]={}；
而上边的定义的是一个结构体的数组，其成员很多。但每一个成员应该和结构体类型一致，这只不是定义一个这样结构类型的结构体数组而已。
看下面例子
typedef struct _TEST_T {int i;char c[10];}TEST_T;TEST_T gst = {1, “12345”};//可以初始化，设置i为1，s为一个字符串.
TEST_T gst = {1};//初始化个数少于实际个数时，只初始化前面的成员。
TEST_Tgst = {.c=“12345”};//有选择的初始化成员。
复合字面量。
gst = (TEST_T){122, "1256"};//这是一个赋值语句，也可以作为初始化。可以出现在程序的任何地方。
当然也可以使用复合字面量来初始化：
gst = (TEST_T){.i=122, .c="123"};
3、结构体数组
可以用多个大括号括起来：
TEST_T gst[10] = {{},{},{},{}}
也可以初始化其中的一个元素：
TEST_T gst[10] = {[2]={}, [3]={}}
也可以使用复合字面量：
TEST_T gst[10] = {[2].i=0, [3].i={}}
