<DT><B>Description</B><DD><P>The <CODE>fileno</CODE> function returns the file handle used
|
|
internally by a C stream. This file handle (an integer) can be used as a

handle for the POSIX input/output functions.</P>

|

<UL>
|
|
<LI>The function is only available as fastcall function, so it may only be

used in presence of a prototype.</LI>
|
|
<LI>Mixing C file I/O functions and POSIX file I/O functions for the same
|
|
file may have unpredictable results.</LI>
