Per-disk current directories

are described by the following structures. These structures can only be modified by the FSD during FS_ATTACH and FS_CHDIR operations.

/* file system independent - current directories */ struct cdfsi { unsigned short cdi_hVPB; /* VPB handle for associated device */ unsigned short cdi_end; /* offset to root of path */ char cdi_flags; /* FS independent flags */ char cdi_curdir[260]; /* text of current directory */ }; /* file system dependent - current directories */ struct cdfsd { char cdd_work[8]; /* work area */ };
