/* this file was adapted for VMS. NOT ALL UNIX FEATURES WORK */
/*
*------> THE DESCRIPTION BELOW IS FOR UNIX... <-----
* Filesystem-independent directory information.
* Directory entry structures are of variable length.
* Each directory entry is a struct dirent containing its file number, the
* offset of the next entry (a cookie interpretable only the filesystem
* type that generated it), the length of the entry, and the length of the
* name contained in the entry. These are followed by the name. The
* entire entry is padded with null bytes to a 4 byte boundary. All names
* are guaranteed null terminated. The maximum length of a name in a
* directory is MAXNAMLEN, plus a null byte.
*------> THE DESCRIPTION BELOW IS FOR VMS... <-----
* for VMS only d_name, d_namlen and d_ino are defined.
* d_fileno is a nonzero number to make you think the file is there. The number
* has no other meaning.
