FILE *out=fopen64("text.txt","w+");
unsigned int write;
char *outbuf=new char[write];
//fill outbuf
printf("%i\n",ftello64(out));
fwrite(outbuf,sizeof(char),write,out);
printf("%i\n",write);
printf("%i\n",ftello64(out));

输出:

0
25755
25868

到底是怎么回事？write设置为25755,我告诉fwrite将多个字节写入文件,这是在开头,然后我在25755以外的位置？
