不能貼Code...會被切掉..因為Code有">" "<"符號？

int execed = 0;



int main(int argc, char *argv[])

{

	char c;

	int _argc = 0;

	char *_argv[3];

	pid_t pid;



	while ((c=getopt(argc, argv, "D"))  > 0) {

		switch(c) {

			case 'D':

				execed = 1;

				break;

			default:

				fprintf(stderr, "You probably don't want to pass "

					"options to this\n");

				exit(1);

		}

	}



	if (!execed) {

		if ((pid = vfork()) .lt. 0) {

			fprintf(stderr, "vfork failed\n");

			exit(1);

		} else if (pid != 0) {

			exit(0);

		}



		_argv[_argc++] = argv[0];

		_argv[_argc++] = "-D";

		_argv[_argc++] = NULL;

		execv(_argv[0], _argv);

		/* Not reached */

		fprintf(stderr, "Couldn't exec\n");

		_exit(1);



	} else {

		setsid();

		chdir("/");

		umask(0);

		close(0);

		close(1);

		close(2);

	}

	

	for (;;) {

		sleep(5);

		syslog(LOG_INFO, "Still sleeping\n");

	}

}

把"<"改成 .lt.後 OK.
