- * Name: mkfifo
- *
- * 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).
- *
- * Inputs:
- * pathname - The full path to the FIFO instance to attach to or to create
- * (if not already created).
- * mode - Ignored for now
- *
- * Return:
- * 0 is returned on success; otherwise, -1 is returned with errno set
- * appropriately.
- *
