How to stop the Windows C library from converting "\r\n" to "\n" when reading a text file in C?

Question

I have a normal text file that lines end with normal \r\n. However, when using 'open' and 'read', Windows convert all the \r\n to \n. I know this means I have to open the file in binary mode but the function 'open' doesn't give this option, it has only read-only, write-only, or read-write.

This is the code:

int File_Size = ...; 
char* Buffer = (char*)malloc(File_Size);

int Handle = open(File_Path,O_RDONLY);
read(Handle,Buffer,File_Size);
close(Handle);

Answer 1

Try using O_RDONLY|O_BINARY.
