VQUOTACTL(2)             DragonFly System Calls Manual            VQUOTACTL(2)


NAME

     vquotactl -- set or return VFS quota data


LIBRARY

     Standard C Library (libc, -lc)


SYNOPSIS

     #include <sys/vfs_quota.h>

     int
     vquotactl(const char *path, struct plistref *pref);


DESCRIPTION

     The vquotactl() call serves as the only kernel/userland VFS quota inter-
     face.  proplib(3) messages specific to the path mount point are sent or
     returned via the pref parameter.

     To use the vquotactl() call, the vfs.quota_enabled tunable needs to be
     set in loader.conf(5).


RETURN VALUES

     The vquotactl() function returns the value 0 if successful; otherwise the
     value -1 is returned and the global variable errno is set to indicate the
     error.


ERRORS

     A vquotactl() call may return the following error codes:

     [EOPNOTSUPP]       VFS quota support has not been enabled at system
                        startup

     [EINVAL]           The message embedded in the pref argument was not
                        understood.


SEE ALSO

     loader.conf(5), vquota(8)


HISTORY

     The vquotactl() function call appeared in DragonFly 2.13.
