This form of the function applies to elements that are of type blob. Handle is returned from `classname_structname_read_handle()`.

### Prototype

>         MCO_RET	structname_fieldname_get(	/*IN*/ structname *handle,
>                              /*IN*/ uint4 start_offset,
>                              /*OUT*/ char *dest,
>                              /*IN*/ uint4 dest_size,
>                              /*OUT*/ uint4 *len );

### Arguments

handle | A pointer to a structname handle
start_offset | The offset from the start of the blob from where reading will begin
dest | A pointer to a buffer to receive the element’s contents
dest_size | The size of the dest buffer
len | A uint4 pointer to receive the number of bytes written to dest
