COPY FROM PROGRAM | ||
Argument | Type | Description |
byte-length | Pointer to long | (Input) For fixed-length formats, this argument indicates the expected byte count of the user-supplied row. For variable-length formats, this indicates the maximum length of a row. |
row | Pointer to char | (Output) Pointer to the row buffer that the user-defined handler fills. |
bytes uses | Pointer to long | Number of bytes of the row filled by the handler. If bytes_used is set to zero, COPY does not call the handler again. On fixed-length formats, Ingres raises an error if a non-zero bytes_used is not equal to byte_length. On variable-length formats, a non-zero bytes_used is ignored. |
