This is how I have implemented a "retry" using the cleancode-email program that
I mentioned earlier today.  


for(;;)
			{
			FILE *capturestderr;
			system(temp);
			capturestderr=openfile(STDERRCAPTURE,"r");
			fseek(capturestderr,0L,SEEK_END);
			if (ftell(capturestderr))
				{
				logtime(log);
				fprintf(log,"%s -- %s ** SEND FAILED ** on
EMAIL MAILOUT, retrying\n",subscription.name,subscription.email); closefile
(capturestderr); sleep(2);
				}
			else
				{
				closefile(capturestderr);
				break;
				}
			}
		remove(STDERRCAPTURE);
