<h1><a name="kap_interrupt_2060"></a>INT 21,40 - Write To File or
Device Using Handle</h1>
<p> AH = 40h</p>
<p> BX = file handle</p>
<p> CX = number of bytes to write, a zero value truncates/extends</p>
<p> the file to the current file position</p>
<p> DS:DX = pointer to write buffer</p>
<p> on return:</p>
<p> AX = number of bytes written if CF not set</p>
<p> = error code if CF set (see ~DOS ERROR CODES~)</p>
<p> - if AX is not equal to CX on return, a partial write
occurred</p>
<p> - this function can be used to truncate a file to the current</p>
<p> file position by writing zero bytes</p>
