View Ref-File11.5.16.39.1  dev_close                                            TOS

 Name:        »dev_close«

 Parameters:

               a0 =     FD *file
               -> d0 =  long errcode

 Description: If fd_refcnt is not 0 already, fd_refcnt must be 
              decremented (this must be accomplished by the MX_DEV). 
              On this occasion any buffers that may be present should 
              be written back and directory entries updated. If 
              fd_refcnt is 0, the FD can be released. At a disk media 
              change fd_refcnt is already 0 at a dev_close call, i.e. 
              the FD just needs to be released.

              The file driver installed by DOS_XFS writes back the 
              directory data and then calls the MX_DDEV subdriver.

 Group:       Workstation driver
