<p>The Get Stream File Size (QHFGETSZ) API returns the current size of a stream file's data, in bytes, as of the last write operation to the file.</p>
|
|
|
|
<br>
|
|
<!-- Please NOTE: DO NOT DELETE THIS SECTION if this API has no authorities and locks. -->
|
|
<!-- Instead, use the commented out coding below to indicate NONE. -->
|
|
<h3>Authorities and Locks</h3>
|
|
|
|
<!-- Use this if there are no authorities and locks. -->
|
|
<p>None.</p>

<h3>Required Parameter Group</h3>
|
|
|
|
<dl>
|
|
<dt><strong>Open file handle</strong></dt>
|
|
|
|
<dd>INPUT; CHAR(16)
|
|
|
|
<p>The file handle returned when the file was opened with the Open Stream File (QHFOPNSF) API.</p>
|
|
</dd>
|
|
|
|
<dt><strong>File size</strong></dt>
|
|
|
|
<dd>OUTPUT; BINARY(4) UNSIGNED
|
|
|
|
<p> The number of bytes of data in the file as of the last write operation. This number is either the last offset written plus 1 or the size set with the Set Stream File Size (QHFSETSZ) API whichever is higher.</p>
|
|
|
|
<p>This size can differ from the value of the QFILSIZE attribute, which is the size of the file as of the last close operation. In addition, it is the size of the file's data only and does not include the size of any object information stored by the file system. If your file system stores object or other information with the file, the file's allocated size is larger than this size.</p>
