Public Member Functions | |
NamedPipe (Context *context) | |
Construct. | |
NamedPipe (Context *context, const String &pipeName, bool isServer) | |
Construct and open in either server or client mode. | |
~NamedPipe () override | |
Destruct and close. | |
unsigned | Read (void *dest, unsigned size) override |
Read bytes from the pipe without blocking if there is less data available. Return number of bytes actually read. | |
unsigned | Seek (unsigned position) override |
Set position. No-op for pipes. | |
unsigned | Write (const void *data, unsigned size) override |
Write bytes to the pipe. Return number of bytes actually written. | |
bool | IsEof () const override |
Return whether pipe has no data available. | |
const String & | GetName () const override |
Return the pipe name. | |
bool | Open (const String &pipeName, bool isServer) |
Open the pipe in either server or client mode. If already open, the existing pipe is closed. For a client end to open successfully the server end must already to be open. Return true if successful. | |
void | Close () |
Close the pipe. Note that once a client has disconnected, the server needs to close and reopen the pipe so that another client can connect. At least on Windows this is not possible to detect automatically, so the communication protocol should include a "bye" message to handle this situation. | |
