主要是要得到IMEI号,但是memcpy(&IMEI_size, (IMEI_entry+4),4);
前已经把IMEI_entry指针加4,相当于加4个IMEI_entry所指的大小字节,而不是4个字节,这一点浪费了我有半天的时间才找到,正确的做法是memcpy(&IMEI_size, (comp_buff+sizeof(FLASH_BUFFER_HEADER)+4),4);//正确代码
,而不是原来的加4。
做一个opcode时竞然不知到取地址符&的用法。
也改了半天。比如int a=8;
int *b;
memcpy(b, a, sizeof(int) );
是错误的,应该第二个参数是指针,但我没想起&,而是用memcpy(b, (int *)a, sizeof(int) );这样也报错,
正确的做法是memcpy(b, &a, sizeof(int) );
