<h2>Error Logging Interface</h2>

<blockquote><pre>
|

void sqlite3_log(int iErrCode, const char *zFormat, ...);
|
||
|
|
</pre></blockquote>
|
||
|
|
<p>
|
||
|
|
The <a href="../c3ref/log.html">sqlite3_log()</a> interface writes a message into the <a href="../errlog.html">error log</a>
|
||
|
|
established by the <a href="../c3ref/c_config_covering_index_scan.html#sqliteconfiglog">SQLITE_CONFIG_LOG</a> option to <a href="../c3ref/config.html">sqlite3_config()</a>.
|
||
|
|
If logging is enabled, the zFormat string and subsequent arguments are
|
||
|
|
used with <a href="../c3ref/mprintf.html">sqlite3_snprintf()</a> to generate the final output string.</p>
|
||
|
|
|
||
|
|
<p>The sqlite3_log() interface is intended for use by extensions such as
|
||
|
|
virtual tables, collating functions, and SQL functions. While there is
|
||
|
|
nothing to prevent an application from calling sqlite3_log(), doing so
|
||
|
|
is considered bad form.</p>
|
||
|
|
|
||
|
|
<p>The zFormat string must not be NULL.</p>
|
||
|
|
|
||
|
|
<p>To avoid deadlocks and other threading problems, the sqlite3_log() routine
|
||
|
|
will not use dynamically allocated memory. The log message is stored in
|
||
|
|
a fixed-length buffer on the stack. If the log message is longer than
|
||
|
|
a few hundred characters, it will be truncated to the length of the
|
||
|
|
buffer.
