|
// 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
|
|
// 703 = Unable to get procedure address from KERNEL32.DLL
