int sqlite3_blob_bytes(sqlite3_blob *);
R-07796-55423:[Returns the size in bytes of the BLOB accessible via the successfully opened BLOB handle in its only argument. ] R-53088-19343:[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.
