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

    NAME
         mount - mount file system

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

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

    DESCRIPTION
         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.

    DIAGNOSTICS
         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.
