Q_SETINFO(2const)                                            Q_SETINFO(2const)

NAME
       Q_SETINFO - set information about quotafile

LIBRARY
       Standard C library (libc, -lc)

SYNOPSIS
       #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
       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
       See quotactl(2).

ERRORS
       See quotactl(2).

STANDARDS
       Linux.

HISTORY
       Linux 2.4.22.

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