| Go package for handling fifos in a sane way. | |
| ``` | |
| // OpenFifo opens a fifo. Returns io.ReadWriteCloser. | |
| // Context can be used to cancel this function until open(2) has not returned. | |
| // Accepted flags: | |
| // - syscall.O_CREAT - create new fifo if one doesn't exist | |
| // - syscall.O_RDONLY - open fifo only from reader side | |
| // - syscall.O_WRONLY - open fifo only from writer side | |
| // - syscall.O_RDWR - open fifo from both sides, never block on syscall level | |
| // - syscall.O_NONBLOCK - return io.ReadWriteCloser even if other side of the | |
| // fifo isn't open. read/write will be connected after the actual fifo is | |
| // open or after fifo is closed. | |
| func OpenFifo(ctx context.Context, fn string, flag int, perm os.FileMode) (io.ReadWriteCloser, error) | |
| // Read from a fifo to a byte array. | |
| func (f *fifo) Read(b []byte) (int, error) | |
| // Write from byte array to a fifo. | |
| func (f *fifo) Write(b []byte) (int, error) | |
| // Close the fifo. Next reads/writes will error. This method can also be used | |
| // before open(2) has returned and fifo was never opened. | |
| func (f *fifo) Close() error | |
