MOUNT(II)                    5/15/74                    MOUNT(II)

     mount - mount file system

     (mount = 21.)
     sys  mount; special; name; rwflag

     mount(special, name, rwflag)
     char *special, *name;

     Mount  announces  to the system that a removable file system
     has been mounted on the block-structured special  file  spe-
     cial; from now on, references to file name will refer to the
     root file on the newly mounted  file  system.   Special  and
     name  are pointers to null-terminated strings containing the
     appropriate path names.

     Name must exist already.  Its old contents are  inaccessible
     while the file system is mounted.

     The  rwflag  argument determines whether the file system can
     be written on; if it is 0 writing is allowed, if non-zero no
     writing  is  done.   Physically write-protected and magnetic
     tape file systems must be mounted read-only or  errors  will
     occur  when access times are updated, whether or not any ex-
     plicit write is attempted.

     mount(VIII), umount(II)

     Error bit (c-bit) set if: special is inaccessible or not  an
     appropriate  file;  name  does not exist; special is already
     mounted; name is in use; there are  already  too  many  file
     systems mounted.
