            if(ret!=0){
                break;
            }
        }
    }
    return ret;
}

上面的代码，无论fileBuffer中的值是什么，写的zip文件中文件的内容全都是CDCDCDCD，求大神帮助啊 C++ ZIP zlib
[解决办法]
byte* fileBuffer =NULL;
unsigned long fileSize = 0;

//fileBuffer 申请内存并赋值
++nCurIndex;
if(ret == 0)
{
ret = zipWriteInFileInZip(hz,fileBuffer,fileSize);
}
zipCloseFileInZip( hz );
if(fileBuffer){
delete [] fileBuffer;
}
怎么申请内存并赋值？
