A language or port monitor's ClosePort function closes a printer port.
hPort [in]Caller-supplied pointer to a port handle.
If the operation succeeds, the function should return TRUE. Otherwise it should return FALSE.
BOOL ClosePort(
_In_ HANDLE hPort
);
Language monitors and port monitor server DLLs are required to define a ClosePort function and include the function's address in a MONITOR2 structure.
The handle received as the function's hPort argument is the port handle that the monitor's OpenPort or OpenPortEx function supplied.
The ClosePort function should close the port by making the received port handle invalid. It should also free all system resources that were allocated by the monitor's OpenPort or OpenPortEx function.
