| DWORD WaitForInputIdle(hProcess, dwTimeout) | |||||
| HANDLE hProcess; | /* process to wait for | */ | |||
| DWORD dwTimeout; | /* timeout time in milliseconds | */ | |||
The WaitForInputIdle function waits until the specified process has no pending user input.
hProcess
Identifies the process to wait for.
dwTimeout
Specifies the timeout time (in milliseconds). If dwTimeout is INFINITE, the function will not return until the process is idle.
The following list shows the possible return values:
| Value | Meaning |
| 0 | The wait was satisfied successfully. |
| WAIT_TIMEOUT | The wait was terminated because the timeout time was reached. |
| 0xFFFFFFFF | An error occurred. Use the GetLastError function to obtain extended error information. |
The WaitForInputIdle function can be used at any time, not just during application startup.
