[issue2010] POSIX message queue mq_open short form always EINVALs

[Venkatesh Srinivas (via DragonFly issue tracker)]

New submission from Venkatesh Srinivas <vsrinivas at dragonflybsd.org>:

Hi,

Using the short form of mq_open(), (omitting the mode and mq attribute
structure) always returns EINVAL. The long form works fine.

DOESNT WORK ================
#include <sys/types.h>
#include <mqueue.h>

main() {
        int i;

        mq_open("naem", O_RDWR|O_CREAT|O_EXCL);

        pause();
}

WORKS ======================
#include <sys/types.h>
#include <mqueue.h>

main() {
	int i;

	mq_open("nam", O_RDWR|O_CREAT|O_EXCL, 0777, NULL);

	pause();
}
