fstream的问题
fstream file_stream;

char* filename=new char[256];
char* filebuf=new char[1025];

::memset(filebuf,0,1025);
::memset(filename,0,256);

memcpy(filename,"e:\\test.txt",256);

file_stream.open(filename,ios::binary,filebuf::sh_read);

if(file_stream.fail())
{
AfxMessageBox("读取失败！");
}
file_stream.getline(filebuf,1024, '\n ');


file_stream.close();

delete filename;
delete filebuf;


提示读取失败，不知道这个类怎么用法？

[解决办法]
ios::binary | ios::in | ios::out,
[解决办法]
将第一行的“fstream file_stream; ”去掉，将第七行的“file_stream.open(filename,ios::binary,filebuf::sh_read); ”改为“fstream file_stream(filename,ios_base::in | ios_base::out | ios_base::trunc);
”你试试看好不好使
