<h2>Report the internal text encoding state of an sqlite3_value object</h2>

<blockquote><pre>
|
|
int sqlite3_value_encoding(sqlite3_value*);
|
|
</pre></blockquote>
|
|
<p>
|
|
The sqlite3_value_encoding(X) interface returns one of <a href="../c3ref/c_any.html">SQLITE_UTF8</a>,
|
|
<a href="../c3ref/c_any.html">SQLITE_UTF16BE</a>, or <a href="../c3ref/c_any.html">SQLITE_UTF16LE</a> according to the current text encoding
|
|
of the value X, assuming that X has type TEXT. If sqlite3_value_type(X)
|
|
returns something other than SQLITE_TEXT, then the return value from
|
|
sqlite3_value_encoding(X) is meaningless. Calls to
|
|
<a href="../c3ref/value_blob.html">sqlite3_value_text(X)</a>, <a href="../c3ref/value_blob.html">sqlite3_value_text16(X)</a>, <a href="../c3ref/value_blob.html">sqlite3_value_text16be(X)</a>,
|
|
<a href="../c3ref/value_blob.html">sqlite3_value_text16le(X)</a>, <a href="../c3ref/value_blob.html">sqlite3_value_bytes(X)</a>, or
|
|
<a href="../c3ref/value_blob.html">sqlite3_value_bytes16(X)</a> might change the encoding of the value X and
|
|
thus change the return from subsequent calls to sqlite3_value_encoding(X).</p>
|
|
|
|
<p>This routine is intended for used by applications that test and validate
|
|
the SQLite implementation. This routine is inquiring about the opaque
|
|
internal state of an <a href="../c3ref/value.html">sqlite3_value</a> object. Ordinary applications should
|
|
not need to know what the internal state of an sqlite3_value object is and
|
|
hence should not need to use this interface.
