Functions ¶
func DestroyUnixFIFO ¶
DestroyUnixFIFO permanently removes the FIFO.
Types ¶
type Fifo ¶
type Fifo interface {
io.ReadWriter
io.Closer
Destroy() error
}
Fifo represents a First-In-First-Out object
Example ¶
testData := []byte{1, 2, 3, 4, 5, 6, 7, 8}
go func() {
fifo, err := New("fifo", os.O_CREATE|os.O_WRONLY, 0666)
if err != nil {
panic("new")
}
defer fifo.Close()
if written, err := fifo.Write(testData); err != nil || written != len(testData) {
panic("write")
}
}()
buff := make([]byte, len(testData))
fifo, err := New("fifo", os.O_CREATE|os.O_RDONLY, 0666)
if err != nil {
panic("new")
}
defer fifo.Close()
if read, err := fifo.Read(buff); err != nil || read != len(testData) {
panic("read")
}
// ensure we've received valid data
for i, b := range buff {
if b != testData[i] {
panic("wrong data")
}
}
Output:
type UnixFifo ¶
type UnixFifo struct {
// contains filtered or unexported fields
}
UnixFifo is a first-in-first-out unix ipc mechanism.
func NewUnixFifo ¶
NewUnixFifo creates a new unix FIFO.
