In the case of synchronous execution, the return value is the exit code of

the process (which terminates by the moment the function returns) and will be

$-1$ if the process couldn't be started and typically 0 if the process

terminated successfully. Also, while waiting for the process to

terminate, wxExecute will call \helpref{wxYield}{wxyield}. The caller

should ensure that this can cause no recursion, in the simples case by

calling \helpref{wxEnableTopLevelWindows(FALSE)}{wxenabletoplevelwindows}.

For asynchronous execution, however, the return value is the process id and

zero value indicates that the command could not be executed.
