quotactl - manipulate disk quotas
SYNOPSIS
#include <sys/fs/ufs_quota.h>
- int ioctl(int fd, Q_QUOTACTL, struct quotcl *qp)
+ int ioctl(int fd, Q_QUOTACTL, struct quotctl *qp);
DESCRIPTION
This ioctl() call manipulates disk quotas. fd is the file descriptor
- returned by the open() system call after opening the quotas file
- (located in the root directory of the filesystem running quotas.)

Q_QUOTACTL is defined in /usr/include/sys/fs/ufs_quota.h. qp is the
address of the quotctl structure which is defined as
