|
int sqlite3_win32_set_directory(
|
|
unsigned long type, /* Identifier for directory being set or reset */
|
|
void *zValue /* New value for directory being set or reset */

<p>
|
|
These interfaces are available only on Windows. The
|
|
<a href="../c3ref/win32_set_directory.html">sqlite3_win32_set_directory</a> interface is used to set the value associated
|
|
with the <a href="../c3ref/temp_directory.html">sqlite3_temp_directory</a> or <a href="../c3ref/data_directory.html">sqlite3_data_directory</a> variable, to
|
|
zValue, depending on the value of the type parameter. The zValue parameter
|
|
should be NULL to cause the previous value to be freed via <a href="../c3ref/free.html">sqlite3_free</a>;
|
|
a non-NULL value will be copied into memory obtained from <a href="../c3ref/free.html">sqlite3_malloc</a>
|
|
prior to being used. The <a href="../c3ref/win32_set_directory.html">sqlite3_win32_set_directory</a> interface returns
|
|
<a href="../rescode.html#ok">SQLITE_OK</a> to indicate success, <a href="../rescode.html#error">SQLITE_ERROR</a> if the type is unsupported,
|
|
or <a href="../rescode.html#nomem">SQLITE_NOMEM</a> if memory could not be allocated. The value of the
|
|
<a href="../c3ref/data_directory.html">sqlite3_data_directory</a> variable is intended to act as a replacement for
|
|
the current directory on the sub-platforms of Win32 where that concept is
|
|
not present, e.g. WinRT and UWP. The <a href="../c3ref/win32_set_directory.html">sqlite3_win32_set_directory8</a> and
|
|
<a href="../c3ref/win32_set_directory.html">sqlite3_win32_set_directory16</a> interfaces behave exactly the same as the
|
|
sqlite3_win32_set_directory interface except the string parameter must be
|
|
UTF-8 or UTF-16, respectively.
