The GetExitCodeProcess function retrieves the termination status of the specified process. BOOL GetExitCodeProcess( HANDLE hProcess, // handle to the process LPDWORD lpExitCode // address to receive termination status );
Parameters hProcess Handle to the process. Windows NT: The handle must have PROCESS_QUERY_INFORMATION access. lpExitCode Pointer to a 32-bit variable to receive the process termination status. Return Values If the function succeeds, the return value is nonzero.If the function fails, the return value is zero. To get extended error information, call GetLastError. Res If the specified process has not terminated, the termination status returned is STILL_ACTIVE. If the process has terminated, the termination status returned may be one of the following: The exit value specified in the ExitProcess or TerminateProcess function. The return value from the main or WinMain function of the process. The exception value for an unhandled exception that caused the process to terminate.
