...ead and the offset within the sector for the next file entry to read. I'm contemplating if I should also keep track of the starting sector of the directory (in case we need to rewinddir()). At the moment, I'm first looking at SYSLINUX (the other disk derivatives are next). It has a struc open_file_t and an array containing these strucs Files. Should I create a new struc, open_dir_t to house the needed data elements, or reuse the existing struc? If I should reuse open_file_t, how should I and should I allocate a new array Dirs or reuse Files? If I don't reuse open_file_t, Dirs will be a...
