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

increment

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.
