* Name: mkfifo2
*
* Description:
* mkfifo() makes a FIFO device driver file with name 'pathname.' Unlike
* Linux, a NuttX FIFO is not a special file type but simply a device
* driver instance. 'mode' specifies the FIFO's permissions.
*
* Once the FIFO has been created by mkfifo(), any thread can open it for
* reading or writing, in the same way as an ordinary file. However, it
* must have been opened from both reading and writing before input or
* output can be performed. This FIFO implementation will block all
* attempts to open a FIFO read-only until at least one thread has opened
* the FIFO for writing.
*
* If all threads that write to the FIFO have closed, subsequent calls to
* read() on the FIFO will return 0 (end-of-file).
*
* NOTE: mkfifo2 is a special, non-standard, NuttX-only interface. Since
* the NuttX FIFOs are based in in-memory, circular buffers, the ability
* to control the size of those buffers is critical for system tuning.
*
* Inputs:
* pathname - The full path to the FIFO instance to attach to or to create
* (if not already created).
* mode - Ignored for now
* bufsize - The size of the in-memory, circular buffer in bytes.
*
* Return:
* 0 is returned on success; otherwise, -1 is returned with errno set
* appropriately.
