Q_SETINFO(2const)                                       Q_SETINFO(2const)

NAME         top

       Q_SETINFO - set information about quotafile

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <sys/quota.h>

       int quotactl(QCMD(Q_SETINFO, type), const char *_Nullable special, 0,
                    caddr_t addr);

       #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_SETINFO, type), 0,
                   struct dqinfo *addr);

DESCRIPTION         top

       Set information about quotafile.

       The addr argument should be a pointer to a dqinfo(2type)
       structure.  The .dqi_valid field of the dqinfo(2type) structure
       indicates the entries in the structure that have been set by the
       caller.

       This operation requires privilege (CAP_SYS_ADMIN).

RETURN VALUE         top

       See quotactl(2).

ERRORS         top

       See quotactl(2).

STANDARDS         top

       Linux.

HISTORY         top

       Linux 2.4.22.

       This operation supersedes the Q_SETGRACE and Q_SETFLAGS operations
       in the previous quota interfaces.
