# OCI-Lob->seek

(no version information, might be only in CVS)

OCI-Lob->seek -- Sets the internal pointer of the large object

## 说明

class OCI-Lob {
bool seek ( int offset [, int whence] )
}

Sets the internal pointer of the large object. Parameter offset indicates the amount of bytes, on which internal pointer should be moved from the position, pointed by whence:

`OCI_SEEK_SET` - sets the position equal to offset
`OCI_SEEK_CUR` - adds offset bytes to the current position
`OCI_SEEK_END` - adds offset bytes to the end of large object (use negative value to move to a position before the end of large object)

如果成功则返回 `TRUE`，失败则返回 `FALSE`。

## 参数

offset

whence
