Q_GETQUOTA(2const)                                     Q_GETQUOTA(2const)

NAME         top

       Q_GETQUOTA - get disk quota limits and current usage for user or
       group

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #include <sys/quota.h>

       int quotactl(QCMD(Q_GETQUOTA, type), const char *_Nullable special,
                    int id, 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_GETQUOTA, type),
                   int id, struct dqblk *addr);

DESCRIPTION         top

       Get disk quota limits and current usage for user or group id.

       The addr argument is a pointer to a dqblk(2type) structure.

       Currently, the kernel fills in all entries of the dqblk(2type)
       structure and marks them as valid in the .dqb_valid field.

       Unprivileged users may retrieve only their own quotas; a
       privileged user (CAP_SYS_ADMIN) can retrieve the quotas of any
       user.

RETURN VALUE         top

       See quotactl(2).

ERRORS         top

       See quotactl(2).

STANDARDS         top

       Linux.

HISTORY         top

       Linux.
