Function:
SetErrorMode
The SetErrorMode function controls whether the system will handle the
specified types of serious errors, or whether the process will handle
them.
Parameters
uMode
[in] Specifies the process error mode. This parameter can be one or more of the following values.
Value Action
0 Use the system default, which is to display all error dialog boxes.
SEM_FAILCRITICALERRORS The system does not display the critical-error-handler message box. Instead,
the system sends the error to the calling process.
SEM_NOOPENFILEERRORBOX The system does not display a message box when it fails to find a file. Instead,
the error is returned to the calling process.
Return Values
The return value is the previous state of the error-mode bit flags.

Function:
GetLastError
GetLastError
The GetLastError function retrieves the calling thread's last-error
code value. The last-error code is maintained on a per-thread
basis. Multiple threads do not overwrite each other's last-error code.
Parameters
This function has no parameters.
Return Values
The return value is the calling thread's last-error code
value. Functions set this value by calling the SetLastError
function. The Return Value section of each reference page notes the
conditions under which the function sets the last-error code.

Function:
