Abstract:
|
|||
|
|
|

Routine Description:
|
|||
|
|
|
|||
|
|
This routine sets the size of a file. It must not return until
|
|||
|
|
the size is guaranteed, therefore, it does a flush.
|
|||
|
|
|
|||
|
|
It is environment specific.
|
|||
|
|
|
|||
|
|
This routine will force execution to the correct thread context.

|
|||
|
|
Arguments:
|
|||
|
|
|
|||
|
|
Hive - Hive we are doing I/O for
|
|||
|
|
|
|||
|
|
FileType - which supporting file to use
|
|||
|
|
|
|||
|
|
FileSize - 32 bit value to set the file's size to
|
|||
|
|
|
|||
|
|
Return Value:
|
|||
|
|
|
|||
|
