Returns the size in bytes of the BLOB accessible via the
|
|
successfully opened <a href="../c3ref/blob.html">BLOB handle</a> in its only argument. The
|
|
incremental blob I/O routines can only read or overwriting existing
|
|
blob content; they cannot change the size of a blob.</p>
|
|
|
|
<p>This routine only works on a <a href="../c3ref/blob.html">BLOB handle</a> which has been created
|
|
by a prior successful call to <a href="../c3ref/blob_open.html">sqlite3_blob_open()</a> and which has not
|
|
been closed by <a href="../c3ref/blob_close.html">sqlite3_blob_close()</a>. Passing any other pointer in
|
|
to this routine results in undefined and probably undesirable behavior.
