// Created: 6/23/2000 (Ravi Kochhar)
// Last modified: 3/10/2002 (RK)
// Please report any problems or bugs to kochhar@physiology.wisc.edu
// The latest version of this routine can be found at:
// http://www.neurophys.wisc.edu/ravi/software/killproc/
// Terminate the process "szToTerminate" if it is currently running
// This works for Win/95/98/ME and also Win/NT/2000/XP
// The process name is case-insensitive, i.e. "notepad.exe" and "NOTEPAD.EXE"
// will both work (for szToTerminate)
// Return codes are as follows:
// 0 = Process was successfully terminated
// 602 = Unable to terminate process for some other reason
// 603 = Process was not currently running
// 604 = No permission to terminate process
// 605 = Unable to load PSAPI.DLL
// 606 = Unable to identify system type
// 607 = Unsupported OS
// 632 = Invalid process name
// 700 = Unable to get procedure address from PSAPI.DLL
// 701 = Unable to get process list, EnumProcesses failed
// 702 = Unable to load KERNEL32.DLL
