<a href="intro.html"><h2>SQLite C Interface</h2></a><h2>Load An Extension</h2><blockquote><pre>int sqlite3_load_extension(
121
sqlite3 *db, /* Load the extension into this database connection */
122
const char *zFile, /* Name of the shared library containing extension */
123
const char *zProc, /* Entry point. Derived from zFile if 0 */
124
char **pzErrMsg /* Put error message here if not 0 */
126
</pre></blockquote><p>
127
This interface loads an SQLite extension library from the named file.</p>
129
<p>The sqlite3_load_extension() interface attempts to load an
130
SQLite extension library contained in the file zFile.</p>
132
<p>The entry point is zProc.
133
zProc may be 0, in which case the name of the entry point
134
defaults to "sqlite3_extension_init".
135
The sqlite3_load_extension() interface returns
136
<a href="../c3ref/c_abort.html">SQLITE_OK</a> on success and <a href="../c3ref/c_abort.html">SQLITE_ERROR</a> if something goes wrong.
137
If an error occurs and pzErrMsg is not 0, then the
138
<a href="../c3ref/load_extension.html">sqlite3_load_extension()</a> interface shall attempt to
139
fill *pzErrMsg with error message text stored in memory
140
obtained from <a href="../c3ref/free.html">sqlite3_malloc()</a>. The calling function
141
should free this memory by calling <a href="../c3ref/free.html">sqlite3_free()</a>.</p>
143
<p>Extension loading must be enabled using
144
<a href="../c3ref/enable_load_extension.html">sqlite3_enable_load_extension()</a> prior to calling this API,
145
otherwise an error will be returned.</p>
147
