CreateFile library error
#6
In 64-bit _UNSIGNED LONG sometimes won't be good enough, and it won't be toward a parameter that expects a pointer. It's because LONG in QB64 is always 32-bit. It needs to be _INTEGER64 or better yet, _OFFSET.

When converting 32-bit code to 64-bit be prepared to turn any LONG or _UNSIGNED LONG into _OFFSET, or less frequently _INTEGER64. But it depends on the context, such as that "size_t" that seems to be declared as different type in each C/C++ header file.

Pointers are really a PITA which is why I gave up soon with C programming. Was repeatedly crashing my computer trying to program a cheap window manager out of the equivalent of SCREEN 0 limited to MS-DOS, many many years ago.
