msgids
msgids(2) System Calls msgids(2)
NAME
msgids - discover all message queue identifiers
SYNOPSIS
#include <sys/msg.h>
int msgids(int *buf, uint_t nids, uint_t *pnids);
DESCRIPTION
The msgids() function copies all active message queue identifiers from the system into the user-defined buffer specified by buf, provided
that the number of such identifiers is not greater than the number of integers the buffer can contain, as specified by nids. If the size
of the buffer is insufficient to contain all of the active message queue identifiers in the system, none are copied.
Whether or not the size of the buffer is sufficient to contain all of them, the number of active message queue identifiers in the system is
copied into the unsigned integer pointed to by pnids.
If nids is 0 or less than the number of active message queue identifiers in the system, buf is ignored.
RETURN VALUES
Upon successful completion, msgids() returns 0. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The msgids() function will fail if:
EFAULT The buf or pnids argument points to an illegal address.
USAGE
The msgids() function returns a snapshot of all the active message queue identifiers in the system. More may be added and some may be
removed before they can be used by the caller.
EXAMPLES
Example 1 msgids() example
This is sample C code indicating how to use the msgids() function (see msgsnap(2)):
void
examine_queues()
{
int *ids = NULL;
uint_t nids = 0;
uint_t n;
int i;
for (;;) {
if (msgids(ids, nids, &n) != 0) {
perror("msgids");
exit(1);
}
if (n <= nids) /* we got them all */
break;
/* we need a bigger buffer */
ids = realloc(ids, (nids = n) * sizeof (int));
}
for (i = 0; i < n; i++)
process_msgid(ids[i]);
free(ids);
}
