Forces the first matching process to close.
Type: Integer or String
Specify either a number (the PID) or a process name:
PID: The Process ID, which is a number that uniquely identifies one specific process (this number is valid only during the lifetime of that process). The PID of a newly launched process can be determined via the Run function. Similarly, the PID of a window can be determined with WinGetPID. ProcessExist can also be used to discover a PID.
Name: The name of a process is usually the same as its executable (without path), e.g. notepad.exe or winword.exe. Since a name might match multiple running processes, only the first process will be operated upon. The name is not case sensitive.
This function returns the Process ID (PID) of the specified process. If a matching process is not found or cannot be manipulated, zero is returned.
Since the process will be abruptly terminated -- possibly interrupting its work at a critical point or resulting in the loss of unsaved data in its windows (if it has any) -- this function should be used only if a process cannot be closed by using WinClose on one of its windows.
