P4API Calls are Synchronous. |

 |
When a calling program executes a P4API call, control is passed to P4API. The call is synchronous. This means that the program will wait until the call has completed before continuing execution. In particular, a Windows calling program will not process Windows messages during that period. Other applications will continue to function, but functions on that application window (such as Close, Maximize/Minimize, and screen repainting) will not take effect until the P4API call has completed.
