Q_SYNC(2const)                                             Q_SYNC(2const)

NAME         top

       Q_SYNC - synchronize on-disk copy of quota usages

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <sys/quota.h>

       int quotactl(QCMD(Q_SYNC, type), const char *_Nullable special, 0, NULL);

       #include <sys/quota.h>    /* Definition of Q_* constants */
       #include <sys/syscall.h>  /* Definition of SYS_* constants */
       #include <unistd.h>

       int syscall(SYS_quotactl_fd, int fd, QCMD(Q_SYNC, type));

DESCRIPTION         top

       Update the on-disk copy of quota usages for a filesystem.

       For quotactl(2), if special is NULL, then all filesystems with
       active quotas are synchronized.  quotactl_fd(2) always
       synchronizes only one filesystem.

RETURN VALUE         top

ERRORS         top
