<p>
The sqlite3_compileoption_used() function returns 0 or 1
indicating whether the specified option was defined at
compile time.  The SQLITE_ prefix may be omitted from the
option name passed to sqlite3_compileoption_used().</p>

<p>The sqlite3_compileoption_get() function allows iterating
over the list of options that were defined at compile time by
returning the N-th compile time option string.  If N is out of range,
sqlite3_compileoption_get() returns a NULL pointer.  The SQLITE_
prefix is omitted from any strings returned by
sqlite3_compileoption_get().</p>

<p>Support for the diagnostic functions sqlite3_compileoption_used()
and sqlite3_compileoption_get() may be omitted by specifying the
<a href="../compile.html#omit_compileoption_diags">SQLITE_OMIT_COMPILEOPTION_DIAGS</a> option at compile time.</p>
