Hey all,
I just had a quick question about the quotactl(3) function and the values it returns in the dqblk structure defined in ufs/ufs/quota.h. From reading the manpage for quotactl, it seems that it is designed to be a way to read and set quotas for users and groups, among other things. I wrote a small C program (see bottom) to use this function, but everything it returns in the dqblk structure seems to be 2x what the actual values are when I use the quota(1) command. I looked at the source for the quota(1) command, and it appears to grab the quota information directly from the users.quota file (see /usr/src/usr.bin/quota.c getufsquota()). Do I have the wrong impression of the quotactl function, or is there some reason why the values returned are twice what they should be?
Thanks,
-Ben
#include <stdio.h>
#include <pwd.h>
#include <sys/types.h>
#include <ufs/ufs/quota.h>
#include <unistd.h>
#include <err.h>
int main ( ) {
struct passwd *entry;
struct dqblk quota;
entry = getpwnam ("sid67");
if (quotactl ("/home", QCMD(Q_GETQUOTA, USRQUOTA), entry->pw_uid, "a)) {
err (1, NULL);
exit (1);
}
printf ("Soft Limit: %d Hard Limit: %d Current: %d\n", quota.dqb_bsoftlimit, quota.dqb_bhardlimit, quota.dqb_curblocks);
exit (0);
}
The output of this program:
Soft Limit: 10240 Hard Limit: 20480 Current: 2
The output of the quota sid67 command:
Disk quotas for user bweaver (uid 2601):
Filesystem blocks quota limit grace files quota limit grace
/home 131 5120 10240 17 0 0
