Differences between Windows and Linux in Chinese this document __linux

Use fopen ("", "WB") or fopen ("", "RB") in binary mode under Windows
B is the meaning of binary mode, B is only valid in Windows, in Linux with the results of R and RB is the same
All text lines under UNIX and Linux end with \ n, and all text lines under windows are ended with \ r \ n
On the Windows platform, open the file in text mode without B:

When the file is read, the system converts all "\ r \ n" to "\ n"

When the file is written, the system converts "\ n" to "\ r \ n" written

When you open a file in binary mode under Windows, neither read nor write makes this conversion
Under the Unix/linux platform, there is no difference between text and binary mode, and "\ r \ n" is entered as two characters.
So, the line breaks for text files under Windows platform are "\ r \ n", and the line breaks under Linux are "\ n"
