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

     special; 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

     explicit write is attempted.



SEE ALSO

     mount (VIII), umount (II)



DIAGNOSTICS

     Error bit (c-bit) set if: special is inaccessible or not  an

     appropriate  file;  name  does not exist; special is already

     mounted; there are already too many file systems mounted.
