 | |
| <blockquote><pre>
 | |
| sqlite3_str *sqlite3_str_new(sqlite3*);
 | |
| </pre></blockquote>
 | |
| <p>
 | |
| The <a href="../c3ref/str_new.html">sqlite3_str_new(D)</a> interface allocates and initializes
 | |
| a new <a href="../c3ref/str.html">sqlite3_str</a> object.  To avoid memory leaks, the object returned by
 | |
| <a href="../c3ref/str_new.html">sqlite3_str_new()</a> must be freed by a subsequent call to
 | |
| <a href="../c3ref/str_finish.html">sqlite3_str_finish(X)</a>.</p>
 | |
| 
 | |
| <p>The <a href="../c3ref/str_new.html">sqlite3_str_new(D)</a> interface always returns a pointer to a
 | |
| valid <a href="../c3ref/str.html">sqlite3_str</a> object, though in the event of an out-of-memory
 | |
| error the returned object might be a special singleton that will
 | |
| silently reject new text, always return SQLITE_NOMEM from
 | |
| <a href="../c3ref/str_errcode.html">sqlite3_str_errcode()</a>, always return 0 for
 | |
| <a href="../c3ref/str_errcode.html">sqlite3_str_length()</a>, and always return NULL from
 | |
| <a href="../c3ref/str_finish.html">sqlite3_str_finish(X)</a>.  It is always safe to use the value
 | |
| returned by <a href="../c3ref/str_new.html">sqlite3_str_new(D)</a> as the sqlite3_str parameter
 | |
| to any of the other <a href="../c3ref/str.html">sqlite3_str</a> methods.</p>
 | |
| 
 | |
| <p>The D parameter to <a href="../c3ref/str_new.html">sqlite3_str_new(D)</a> may be NULL.  If the
 | |
| D parameter in <a href="../c3ref/str_new.html">sqlite3_str_new(D)</a> is not NULL, then the maximum
 | |
| length of the string contained in the <a href="../c3ref/str.html">sqlite3_str</a> object will be
 | |
| the value set for <a href="../c3ref/limit.html">sqlite3_limit</a>(D,<a href="../c3ref/c_limit_attached.html#sqlitelimitlength">SQLITE_LIMIT_LENGTH</a>) instead
 | |
| of <a href="../limits.html#max_length">SQLITE_MAX_LENGTH</a>.
