#include <sys/quota.h>
```

**int quotactl(QCMD(Q\_XSETQLIM,** *type***), const char \*\_Nullable** *special***,**              **int** *id***, caddr\_t** *addr***);**

**#include \<xfs/xqm.h\>**      /\* See [quotactl\_fd(2)](/quotactl_fd/2.md) \*/ **#include \<sys/syscall.h\>**  /\* Definition of **SYS\_\*** constants \*/ **#include \<unistd.h\>**

**int syscall(SYS\_quotactl\_fd, int** *fd***, QCMD(Q\_XSETQLIM,** *type***),**             **int** *id***, struct fs\_disk\_quota \****addr***);**

## DESCRIPTION

The *addr* argument is a pointer to an [**fs\_disk\_quota**(2type)](/fs_disk_quota/2type.md) structure.

This operation requires privilege (**CAP\_SYS\_ADMIN**).
