On Unix, there is no such distinction. On Windows, any programwhich uses files must know whether each file is text or binary, and openand use them accordingly.</P><P>In a text file on Windows, each line is terminated with a carriagereturn character followed by a line feed character. When the file isread by a C program in text mode, the C library converts each carriagereturn/line feed pair into a single line feed character. If the file isread in binary mode, the program will see both the carriage return andthe line feed.</P><P>You may have seen this distinction when transferring files between Unixand Window systems via <FONT SIZE="-1">FTP</FONT>. You need to set the <FONT SIZE="-1">FTP</FONT>program into binary or text mode as appropriate for the file you want totransfer.</P><P>When transferring a binary file, the <FONT SIZE="-1">FTP</FONT> program simplytransfers the data unchanged. When transferring a text file, the<FONT SIZE="-1">FTP</FONT> program must convert each carriage return/line feed pairinto a single line feed.</P><P>When using the C standard library, a binary file is indicated by adding<KBD>b</KBD> after the <KBD>r</KBD>, <KBD>w</KBD>, or <KBD>a</KBD> in the call to<CODE>fopen</CODE>. When reading a text file, the program can not simplycount characters and use that when computing arguments to <CODE>fseek</CODE>.</P><P><A NAME="Unix/Windows Filesystems"></A></TR></TABLE><BR> <FONT SIZE="-1">This document was generatedby <I>Gary V.
