PROC_NICE(3)								 1							      PROC_NICE(3)

proc_nice - Change the priority of the current process

SYNOPSIS

       bool proc_nice (int  $increment)

DESCRIPTION

       proc_nice(3) changes the priority of the current process by the amount specified in $increment. A positive $increment will lower the prior-
       ity of the current process, whereas a negative $increment will raise the priority.

       proc_nice(3) is not related to proc_open(3) and its associated functions in any way.

PARAMETERS

	      o $increment
		- The increment value of the priority change.

RETURN VALUES

	Returns TRUE on success or FALSE on failure. If an error occurs, like the user lacks permission to change the priority, an error of  level
       E_WARNING is also generated.

NOTES

       Note

	      Availability

	      proc_nice(3) will only exist if your system has 'nice' capabilities. 'nice' conforms to: SVr4, SVID EXT, AT&T, X/OPEN, BSD 4.3. This
	      means that proc_nice(3) is not available on Windows.

NAME

     nice -- execute a utility with an altered scheduling priority

SYNOPSIS

     nice [-n increment] utility [argument ...]

DESCRIPTION

     nice runs utility at an altered scheduling priority.  If an increment is given, it is used; otherwise an increment of 10 is assumed.  The
     super-user can run utilities with priorities higher than normal by using a negative increment.  The priority can be adjusted over a range of
     -20 (the highest) to 20 (the lowest).  A priority of 19 or 20 will prevent a process from taking any cycles from others at nice 0 or better.

     Available options:

     -n increment
	     A positive or negative decimal integer used to modify the system scheduling priority of utility.

EXIT STATUS

     The nice utility exits with one of the following values:

     1-125   An error occurred in the nice utility.

     126     The utility was found but could not be invoked.

     127     The utility could not be found.

     Otherwise, the exit status of nice will be that of utility.

COMPATIBILITY

     The historic -increment option has been deprecated but is still supported in this implementation.

SEE ALSO

     csh(1), getpriority(2), setpriority(2), renice(8)

STANDARDS

     The nice utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').

HISTORY

     A nice utility appeared in Version 6 AT&T UNIX.

BUGS

     nice is built into csh(1) with a slightly different syntax than described here.  The form 'nice +10' nices to positive nice, and 'nice -10'
     can be used by the super-user to give a process more of the processor.
