问题是读取的文件数据合并字符串后,然后写入另一个文件比较后不一样!如果是文本文件容易些,这zip文件不一样
int CountByte=100; //读取100字节
FILE *FromF,*ToF;
FromF = fopen("f:\\unzip100.zip","rb");
char *Smallbuf=(char *)SysGetMem(CountByte);
fread(Smallbuf, CountByte, 1, FromF);
//-----------写入文件并增加3字节ABC,也就是共植入103字节-------------
strcat(Smallbuf,"ABC");
ToF = fopen("f:\\abc.zip","wb");
fwrite(Smallbuf,CountByte+3, 1, ToF); //增加3个字符写入文件中
SysFreeMem(Smallbuf);
fclose(FromF);
fclose(ToF);
