I was speaking as a longtime Mac user. My experience with mkisofs and
hfs is limited.
This is from mkisofs (hfs.c). It looks to me like it's setting one bit
somewhere. Probably, looking through hfsutils (which I haven't done),
you could find the similar code and figure out how to add a routine
that would give you that info back. Or, since this says it's adapted
from vsetattr(), maybe there's a vgetattr floating around out there
somewhere.
/*
* NAME: hfs->vsetbless()
* DESCRIPTION: set blessed folder
*
* adapted from vsetattr() from v3.2.6
*/
#ifdef PROTOTYPES
void
hfs_vsetbless(hfsvol *vol, unsigned long cnid)
#else
void
hfs_vsetbless(vol, cnid)
hfsvol *vol;
unsigned long cnid;
#endif
{
vol->mdb.drFndrInfo[0] = cnid;
vol->flags |= HFS_UPDATE_MDB;
}
