Notes: Use this HFileInfo structure in calls to PBGetCatInfo and
PBSetCatInfo when you access information about a file.
Wherever a function exists to modify one of the values in this structure,
you should use that function. For instance, don't use PBSetCatInfo to set
the lock bit; instead call PBSetFLock.
A common way to use this structure is to allocate a CInfoPBRec union
which is an aggregate of HFileInfo and DirInfo. Create and initialize a
pointer to each data type and use either structure in the call to
PBGetCatInfo. Upon return, check bit 4 of ioFlAttrib. If bit 4 is set,
then the return data is about a directory and you should use the DirInfo
structure; otherwise, use HFileInfo. See CInfoPBRec for examples.
