Function sqlite3_column_blob 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn sqlite3_column_blob(
    stmt: *mut Sqlite3Stmt,
    i_col: c_int,
) -> *const c_void

Get a blob pointer from column i_col.

The returned pointer is valid until the next sqlite3_step, sqlite3_reset, or sqlite3_finalize on this statement.

Safety

stmt must be a valid handle with an active row.
