ifx_lo_truncate(lofd, offset)
The function accepts the following arguments.
| Argument | Type | Use | Description |
|---|---|---|---|
| lofd | SQL_INTEGER | Input | Smart-large-object file descriptor |
| offset | SQL_BIGINT | Input | End of the smart large object. If this value exceeds
the end of the smart large object, the function extends the smart
large object. If this value is less than the end of the smart large object,
the database server reclaims all storage from the offset position
to the end of the smart large object.
Instead of using the default Informix ODBC Driver C data type of SQL_C_CHAR for offset, use SQL_C_LONG or SQL_C_SHORT. For more information, see SQL_BIGINT. |
The ifx_lo_truncate() function sets the end of a smart large object to the location that the offset argument specifies.
