SuperBike.cpp

Abstract:
|
||
|
|
|
||
|
|
The application attempts to convert the path to the executable into the directory
|
||
|
|
containing the executable by replacing the last \ in the path with NULL.
|
||
|
|
Unfortunately, they start not at the end of the string, but at the max length
|
||
|
|
of the string. On Win9x the extra memory doesn't (coincidentally) have a \,
|
||
|
|
so the proper string is passed as the CWD to CreateProcessA. On Whistler,
|
||
|
|
the extra memory contains a \ so they end up changing nothing.
