This program spawns two threads. The threads signal each other repeatedly for a specified length of time. When time expires, the main thread signals the threads to complete and ends the program.
Source Files
| File | Description |
|---|---|
PingPong.cpp

Unexpected Results
There should not be consecutive Ping! or Pong! messages.
Remarks
- This sample uses three event objects shared between the two threads: two for signaling Ping and Pong operations, and one each for indicating thread completion.
- Events are auto-reset events (non-manual reset), ensuring threads proceed in turn.
- A short sleep (100 ms) at the start of each thread prevents output messages from interleaving.
- The main thread waits indefinitely for both threads to signal completion before closing handles and exiting.
