	It is recommended that version be checked before using LHA.DLL.

-----------------------------------------------------------------------
BOOL FAR PASCAL LhaGetRunning(void)
-----------------------------------------------------------------------
Description:	Check if LHA.DLL is currently running.
		Current version of LHA.DLL does not support multiprocessing.
Return Value:
	TRUE	LHA.DLL is already running.

Description:	Set LHA.DLL to run in background mode.
		LHA.DLL will compress/decompress file faster in foreground
		mode, but does not permit multi-processing.
Parameter:
	TRUE	Run LHA.DLL in background mode
	FALSE	Do not run LHA.DLL in background
Return Value:
	TRUE	No error
	FALSE	Unable to change mode or parameter error.
Warning:
	To maintain compatibility between version 1.0x, please turn off
	background mode:
		LhaSetBackGroundMode(FALSE);

Description:	Set LHA.DLL to either display or not display cursor
Parameter:
	TRUE	Display cursor
	FALSE	Do not display cursor
Return Value:
	TRUE	No error
	FALSE	Unable to change mode or parameter error
Warning:
	To maintain compatibility between version 1.0x, please display
	cursor:
		LhaSetCursorMode(TRUE);
	However, if you are running LHA.DLL in the background mode,
	turn of the cursor:
		LhaSetCursorMode(FALSE);
