The information in this article applies to:

The C Run-time (CRT), included with:

    - Microsoft C for MS-DOS, versions 5.1, 6.0, 6.0a, and 6.0ax
    - Microsoft C for OS/2, versions 5.1, 6.0, and 6.0a
    - Microsoft C/C++ for MS-DOS, version 7.0
    - Microsoft Visual C++ for Windows, versions 1.0 and 1.5

An application compiled in the small or medium memory model can use one of the printf() functions to display a far string or a far pointer. To do so, modify the %s or %p field with an uppercase "F" character.

For example, if an application contains the following declaration:

   char far *ptr;

an application compiled in the small or medium memory model can display the value of the pointer with the following function call:

   printf("%Fp", ptr);

If ptr points to a data string, the following function call displays the value of the string:

   printf("%Fs", ptr);

For additional information about using the F specifier with the printf() functions, refer to the C run-time library reference manual or to the online help file distributed with your language compiler.
