VFS_QUOTACTL(9)        FreeBSD Kernel Developer's Manual       VFS_QUOTACTL(9)

NAME

     VFS_QUOTACTL - manipulate file system quotas

SYNOPSIS

     #include <sys/param.h>
     #include <sys/mount.h>
     #include <sys/vnode.h>

     int
     VFS_QUOTACTL(struct mount *mp, int cmds, uid_t uid, void *arg,
         bool *mp_busy);

DESCRIPTION

     Implement file system quotas.

     The mp_busy argument is an input/output parameter.  VFS_QUOTACTL() must
     be called with mp marked busy through vfs_busy(9) and *mp_busy set to
     true.  The filesystem implementation of VFS_QUOTACTL() may then unbusy mp
     using vfs_unbusy(9) prior to performing quota file I/O.  In this case the
     implementation must set *mp_busy to false to indicate that the caller
     must not unbusy mp upon completion of VFS_QUOTACTL().

     See quotactl(2) for a description of the remaining arguments.
