 *	Given a HANDLE to a child process, return the process id for that

 *
 * Results:
 *	Returns the process id for the child process. If the pid was not known
 *	by Tcl, either because the pid was not created by Tcl or the child
 *	process has already been reaped, (size_t)-1 is returned.
 *	process has already been reaped, TCL_IO_FAILURE is returned.
 *
 * Side effects:
 *	None.
