FNC_LobLength_t FNC_LobOpen ( LOB_LOCATOR object, LOB_CONTEXT_ID *ctxid, FNC_LobLength_t start, FNC_LobLength_t maxlength )
- LOB_LOCATOR object
- the object.
- LOB_CONTEXT_ID *ctxid
- a context identifier.
- FNC_LobLength_t start
- the starting byte offset, relative to 0, for the read operation. If this value is greater than or equal to the length of the object, then the resulting data stream will have a zero length.
- FNC_LobLength_t maxlength
- the maximum number of bytes to read. If this value is 0, or if start + maxlength is greater than the object length, then the read operation terminates when the length of the object is exhausted.
