     sqlite3_blob_bytes - Return The Size Of An Open BLOB

     sqlite3_blob_bytes(sqlite3_blob *);

     Returns the size in bytes of the BLOB accessible via the successfully
     opened BLOB handle 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.

     This routine only works on a BLOB handle which has been created by a
     prior successful call to sqlite3_blob_open() and which has not been
     closed by sqlite3_blob_close().  Passing any other pointer in to this
     routine results in undefined and probably undesirable behavior.
