     In the open() function call, binary mode can be specified with the flag
     O_BINARY and text mode with O_TEXT. These symbols are defined in fcntl.h.

     In the fopen() function call, binary mode can be specified by adding
     a b to the mode string. Text mode is specified by adding a t to the
     mode string.

     The mode of a file can be changed by the call setmode(fd,mode) where fd
     is a file descriptor (an integer) and mode is O_BINARY or O_TEXT. The
     function returns O_BINARY or O_TEXT depending on the mode before the call,
     and EOF on error.
