# rt\_task\_ipc\_delete(2)

delete a real-time task created with rt\_task\_ipc\_init

## NAME

rt\_task\_ipc\_delete - delete a real-time task created with rt\_task\_ipc\_init

## SYNOPSIS

```
#define MODULE
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/version.h>
#include <linux/errno.h>
#include <linux/rtf.h>
#include rt_ipc.h
```

**int rt\_task\_ipc\_delete(RT\_TASK\_IPC \*** *task***);**

## DESCRIPTION

**rt\_task\_ipc\_delete** deletes a real-time task previously created by a call to **rt\_task\_ipc\_init.** **rt\_task\_ipc\_delete** should be used instead of the standard Real-Time Linux function **rt\_task\_delete** for tasks created with  **rt\_task\_ipc\_create**. *task* is the structure with which the task was originally created. If the task was blocked at an **rt\_sem\_wait**, **rt\_mq\_send**, or **rt\_mq\_receive** call, the task is removed from the semaphore or message queue wait queue.

## RETURN VALUE

On success, 0 is returned.  On failure, a negative value is returned as described below.

## ERRORS

- **-EINVAL**

  *task* does not refer to a valid task.
