ROUNDUP(9)						   BSD Kernel Developer's Manual						ROUNDUP(9)

NAME

     roundup -- macros for counting and rounding

SYNOPSIS

     #include <sys/param.h>

     size
     howmany(x, size);

     size
     roundup(x, size);

     size
     rounddown(x, size);

     size
     roundup2(x, size);

     int
     powerof2(x);

DESCRIPTION

     The roundup() and rounddown() macros return an integer from rounding x up and down, respectively, to the next size.  The howmany() macro in
     turn reveals how many times size fits into x, rounding the residual up.

     The roundup2() macro also rounds up, but with the assumption that size is a power of two.	If x is indeed a power of two, powerof2() return
     1.

RETURN VALUES

     The return value is an integer from the respective operation.  If x is 0, all macros except powerof2() return 0.  The behavior is undefined
     if size is 0.

EXAMPLES

     The following example rounds the variable rx to a 32-bit boundary:

	   uint16_t rx;

	   ...

	   rx = roundup2(rx, sizeof(uint32_t));

SEE ALSO

     ilog2(3), param(3), imax(9)

CAVEATS

     All described macros make no assumptions about the type of the parameters.  These are implicitly assumed to be unsigned integers.

ROUNDUP-CTL(1)						      General Commands Manual						    ROUNDUP-CTL(1)

NAME

       roundup-ctl - roundup server control interface

SYNOPSIS

       roundup-ctl [options] command

DESCRIPTION

       roundup-ctl  is	a front end to the roundup server.  It is designed to help the administrator control the functioning of the roundup server
       daemon. This script mimics most of the behaviour of a regular init script, but works as a front end to the runit  package  to  control  the
       roundup	service. So, in order to use this, you need the runit package, too. Please note that using this script is mostly incompatible with
       having roundup controlled by runit directly in the form of automatic startup.

       The roundup-ctl script returns a 0 exit value on success, and >0 if an error occurs. For more details, view the comments in the script.

OPTIONS

       -d directory
	      Use given directory as service directory.

COMMANDS

       The command can be any one or more of the following options:

       start  If the roundup server is not runinng, start it. If the server stops, restart it.	stop Stops the roundup server.	status Print  sta-
	      tus of the roundup server.
