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 at an altered scheduling priority

SYNOPSIS

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

DESCRIPTION

     The nice utility runs utility at an altered scheduling priority, by incrementing its ``nice'' value by the specified increment, or a default
     value of 10.  The lower the nice value of a process, the higher its scheduling priority.

     The superuser may specify a negative increment in order to run a utility with a higher scheduling priority.

     Some shells may provide a builtin nice command which is similar or identical to this utility.  Consult the builtin(1) manual page.

ENVIRONMENT

     The PATH environment variable is used to locate the requested utility if the name contains no '/' characters.

EXAMPLES

     Execute utility 'date' at priority 5 assuming the priority of the shell is 0:

	   nice -n 5 date

     Execute utility 'date' at priority -19 assuming the priority of the shell is 0 and you are the super-user:

	   nice -n 16 nice -n -35 date

DIAGNOSTICS

     If utility is invoked, the exit status of nice is the exit status of utility.

     An exit status of 126 indicates utility was found, but could not be executed.  An exit status of 127 indicates utility could not be found.

COMPATIBILITY

     The traditional -increment option has been deprecated but is still supported.

STANDARDS

     The nice utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY

     A nice utility appeared in Version 4 AT&T UNIX.
