Linux 和 Windows 中 fopen 打开方式的区别

The mode string can also include the letter 'b' either as a last character or as a character between the characters in any of the two-character strings described above.  This is strictly for compatibility with C89 and has no effect; the 'b' is ignored on all POSIX conforming systems, including Linux.  (Other systems may treat text files and binary files differently, and adding the 'b' may be a good idea if you do I/O to a

binary file and expect that your program may be ported to non-UNIX environments.)
