proc_nice (PHP 5) proc_nice -- Change the priority of the current process 说明bool proc_nice ( int increment )
proc_nice() changes the priority of the current
process by the amount specified in increment. A
positive increment will lower the priority of the
current process, whereas a negative increment
will raise the priority.
proc_nice() is not related to
proc_open() and its associated functions in any way.
参数

The increment value of the priority change.
返回值
如果成功则返回 TRUE,失败则返回 FALSE。
If an error occurs, like the user lacks permission to change the priority,
an error of level E_WARNING is also generated.
注释Availability:
proc_nice() 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() is not available
on Windows.
