Wait for an event.

## Declaration

Source position: threadh.inc line 182

`procedure RTLEventWaitFor(`
`state: PRTLEvent`
`); procedure RTLEventWaitFor(`
`state: PRTLEvent;`
`timeout: LongInt`
`);`

## Description

RTLeventWaitFor suspends the thread till the event occurs. The event will occur when another thread calls RTLEventSetEvent on State.

By default, the thread will be suspended indefinitely. However, if TimeOut is specified, then the thread will resume after timeout milliseconds have elapsed.
