mqcreate1.c

基于unix/linux 的消息队列编程；库采用POSIX 可做商业源代码用

#include	"unpipc.h"

int
main(int argc, char **argv)
{
	int		c, flags;
	mqd_t	mqd;

	flags = O_RDWR | O_CREAT;
	while ( (c = Getopt(argc, argv, "e")) != -1) {
		switch (c) {
		case 'e':
			flags |= O_EXCL;
			break;
		}
	}
	if (optind != argc - 1)
		err_quit("usage: mqcreate [ -e ] <name>");

	mqd = Mq_open(argv[optind], flags, FILE_MODE, NULL);

	Mq_close(mqd);
	exit(0);
