This function returns the flags associated with the file handle passed in parameter 1.
The following flags are currently defined:
HWFOPENFLAGS_STREAMING:
If this flag is set, the file is being streamed from a network source. This means that
you should try to avoid operations that are inefficient on streaming sources like excessive
seeking operations.
HWFOPENFLAGS_NOSEEK:
If this flag is set, you won't be able to seek the file. This means that most calls to
hw_FSeek() will fail. The only operations that are still supported
by hw_FSeek() are rewinding (i.e. reverting the read/write cursor to
the beginning of the file) and querying the current file cursor position. If you want
hw_FSeek() to work on files with HWFOPENFLAGS_NOSEEK set too, you
may want to set the HWFOPENMODE_EMULATESEEK flag, although this can be very inefficient.
See hw_FOpen for details.
