CreateFileA/CreateFileW return type 'HANDLE' while TIFFFdOpen() takes 'int',
|
|
which is formally incompatible and can even seemingly be of different size:
|
|
HANDLE is 64 bit under Win64, while int is still 32 bits there.
|
|
|
|
However, only the lower 32 bits of a HANDLE are significant under Win64 as,
|
|
for interoperability reasons, they must have the same values in 32- and
|
|
64-bit programs running on the same system, see
|
|
|
|
https://docs.microsoft.com/en-us/windows/win32/winprog64/interprocess-communication
|
|
|
|
Because of this, it is safe to define the following trivial functions for
|
|
casting between ints and HANDLEs, which are only really needed to avoid
|
|
compiler warnings (and, perhaps, to make the code slightly more clear).
|
|
Note that using the intermediate cast to "intptr_t" is crucial for warning
|
|
avoidance, as this integer type has the same size as HANDLE in all builds.
