NAME
       dgmknod - data returned by the dg_mknod system call

SYNOPSIS
       #include <sys/dgmknod.h> #include <sys/types.h>

DESCRIPTION
       The system call dgmknod takes a parameter that is a pointer to the
       structure defined by this include file.  This structure defines the
       node that is created.

          struct  dgmknod
          {
            modet         extendedmode;
            devt          devicenumber;
            char *         symboliclinktarget;
            unsigned long  desireddataelementblocks;
            unsigned long  dataelementblockslimit;
            unsigned long  desiredindexelementblocks;
            unsigned long  indexelementblockslimit;
          };


       The fields of this structure are defined as follows:

       extendedmode
              The file type and access permissions of the file.  The file
              type is available by AND-ing this field with
              DG_FILE_TYPE_MASK.  The access bits are available by AND-ing
              this field with (~ DG_FILE_TYPE_MASK).  The file type and
              access are encoded using the constants defined in stat.h and
              dg_stat.h

       devicenumber
              The device specifier to be used if the file to be created is
              of type `block-special' or `character-special'.  This field is
              ignored otherwise.

       symbolictargetlink
              A null-terminated pathname which will be the target of the
              file to be created if that file is of type `symbolic link'.
              This field is ignored otherwise.

       desireddataelementblocks
              The preferred size (in 512-byte blocks) of the data elements
              of the file to be created.  If this size is 0, then the
              default data element size for the containing file system will
              be used.

       dataelementblockslimit
              The maximum size (in 512-byte blocks) of the data elements of
              the file to be created.  Values in the range starting at the
              preferred size and working towards the limit are tried until a
              valid data element size is found.

       desiredindexelementblocks
              The preferred size (in 512-byte blocks) of the index elements
              of the file to be created.  If this size is 0, then the
              default data element size for the containing file system will
              be used.

       indexelementblockslimit
              The maximum size (in 512-byte blocks) of the index elements of
              the file to be created.  Values in the range starting at the
              preferred size and working towards the limit are tried until a
              valid data element size is found.
