rtf_ipc_destroy2
Destroy a real-time fifo
Usage
#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 rtf_ipc_destroy(unsigned int fifo);
Overview
rtf_ipc_destroy removes a real-time fifo (RT-FIFO) previously created with rtf_ipc_create(2). fifo is then available for reuse by another call to rtf_ipc_create(2).
The rt_ipc RT-FIFO is a mechanism, implemented as a character device, to communicate between real-time tasks and ordinary Linux processes. It is based on the Real-Time Linux RT-FIFO mechanism. The rtf_* functions are used by the real-time tasks; Linux processes use standard character device access functions such as read(2), write(2), and select(2).
Return value
On success, 0 is returned. On failure, a negative value is returned as described below.
Errors
-EINVAL-
fifo is not a valid RT-FIFO identifier.
