## 例

`

     bool proc_nice ( int $increment )

`

## 説明

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.

## 戻り値

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.
