使用CFile检查换行符（换行符）

Question

I need to check whether a file is ended with a line break or not, using CFile . What I have tried:

1. point the file pointer at the end of the file
2. move the pointer back by 2 units
3. check if the pointer is pointing at \\r\\n

Here is my code:

cfile.SeekToEnd();
cfile.Seek(-2, CFile::current);
char buffer[2];
cfile.Read(buffer, 2);
if(buffer[0] == '\r' && buffer[1] == '\n') printf("Ended with line break!");
else printf("Not ended with line break!");

However, what I found is that the buffer gives me a \\n character and a garbage character (with weird values like 204). After some research through the documentation, I found that CFile::Read only count \\r\\n as a single character:

For text-mode files, carriage return–linefeed pairs are counted as single characters.

I am so confused because the file pointer obviously still counts 2 characters but I cannot get both of them. Is there any method to check line break at the end of a file with CFile?

Answer 1

I solved the problem by using CFile::typeBinary when opening a file.

It seems that CFile::typeText do something special processing carriage return–linefeed pairs (eg filling in a garbage character which is supposed to be a carriage return) which is not desired in my case.
