proc_nice — Change the priority of the current process

### 설명

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.

### 인수

`increment`

  The increment value of the priority change.

### 반환값

성공할 경우 `TRUE`를, 실패할 경우 `FALSE`를 반환합니다. If an error occurs, like the user lacks permission to change the priority, an error of level `E_WARNING` is also generated.
