setquota(2)							System Calls Manual						       setquota(2)

Name
       setquota - enable/disable quotas on a file system

Syntax
       setquota(special, file)
       char *special, *file;

Description
       Disk quotas are enabled or disabled with the call.  The special indicates a block special device on which a mounted file system exists.	If
       file is nonzero, it specifies a file in that file system from which to take the quotas.	If file is zero, then quotas are disabled  on  the
       file system.  The quota file must exist; it is normally created with the program.

       Only the superuser can turn quotas on or off.

Return Values
       A zero (0) return value indicates a successful call.  A value of -1 is returned when an error occurs, and errno is set to indicate the rea-
       son for failure.

Diagnostics
       The system call fails when one of the following occurs:

       [ENODEV]       The special does not exist.

       [ENOTBLK]      The special is not a block device.

       [ENXIO]	      The major device number of special is out of range. (This indicates no device driver exists for the associated hardware.)

       [ENOTDIR]      A component of either path prefix is not a directory.

       [EROFS]	      The file resides on a read-only file system.

       [EACCES]       The file resides on a file system different from special.

       [EACCES]       The file is not a plain file.

       [EINVAL]       Either pathname contains a character with the high-order bit set.

       [EINVAL]       The kernel has not been compiled with the QUOTA option.

       [ENAMETOOLONG] A component of either pathname exceeded 255 characters, or the entire length of either path name exceeded 1023 characters.

       [ENOENT]       The file does not exist.

       [ELOOP]	      Too many symbolic links were encountered in translating either pathname.

       [EPERM]	      The caller is not the superuser.

       [EACCES]       Search permission is denied for a component of either path prefix.

       [EIO]	      An I/O error occurred while reading from or writing to the file containing the quotas.

       [EFAULT]       The special or path points outside the process's allocated address space.

NAME

     swapon -- add a swap device for interleaved paging/swapping

SYNOPSIS

     #include <unistd.h>

     int
     swapon(const char *special);

DESCRIPTION

     This interface is provided for compatibility only and has been obsoleted by swapctl(2).

     swapon() makes the block device special available to the system for allocation for paging and swapping.  The names of potentially available
     devices are known to the system and defined at system configuration time.	The size of the swap area on special is calculated at the time the
     device is first made available for swapping.

RETURN VALUES

     If an error has occurred, a value of -1 is returned and errno is set to indicate the error.

ERRORS

     swapon() succeeds unless:

     [ENOTDIR]	   A component of the path prefix is not a directory.

     [ENAMETOOLONG]
		   A component of a pathname exceeded {NAME_MAX} characters, or an entire path name exceeded {PATH_MAX} characters.

     [ENOENT]	   The named device does not exist.

     [EACCES]	   Search permission is denied for a component of the path prefix.

     [ELOOP]	   Too many symbolic links were encountered in translating the pathname.

     [EPERM]	   The caller is not the super-user.

     [ENOTBLK]	   special is not a block device.

     [EBUSY]	   The device specified by special has already been made available for swapping

     [EINVAL]	   The device configured by special was not configured into the system as a swap device.

     [ENXIO]	   The major device number of special is out of range (this indicates no device driver exists for the associated hardware).

     [EIO]	   An I/O error occurred while opening the swap device.

     [EFAULT]	   special points outside the process's allocated address space.

SEE ALSO

HISTORY

     The swapon() function call appeared in 4.0BSD and was removed NetBSD 1.3

BUGS

     This call will be upgraded in future versions of the system.
