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; name is in use; there are already too many file systems mounted.
