Results
The result type is INTEGER(4). The result is zero if successful; otherwise, a Windows* error value.
This routine must not be used when any I/O is pending. Since a read operation is always pending after any I/O has been started, you must first call SPORT_CANCEL_IO before port parameters can be changed.
Example
USE IFPORT
INTEGER(4) iresult
iresult = SPORT_SHOW_STATE( 2, 0 )
