Public Member Functions | |
| NamedPipe (Context *context) | |
| Construct. | |
| NamedPipe (Context *context, const String &name, bool isServer) | |
| Construct and open in either server or client mode. | |
| ~NamedPipe () override | |
| Destruct and close. | |
| i32 | Read (void *dest, i32 size) override |
| Read bytes from the pipe without blocking if there is less data available. Return number of bytes actually read. More... | |
| i64 | Seek (i64 position) override |

| void | SetName (const String &name) override |

| bool | Open (const String &name, bool isServer) |

| void | Close () |
