<!-- ##### SECTION Title ##### -->
quota
<!-- ##### SECTION Short_Description ##### -->
Functions for manipulating disk quotas.
<!-- ##### SECTION Long_Description ##### -->
<para>
quota.h declares functions which are useful for querying and manipulating
user and group disk quotas under Linux. These routines are not portable
to other operating systems.
</para>
<!-- ##### SECTION See_Also ##### -->
<para>
</para>
<!-- ##### SECTION Stability_Level ##### -->
<!-- ##### FUNCTION quota_on ##### -->
<para>
Enables enforcing quotas on filesystems where quotas are configured.
</para>
@Returns: 0 on success, -1 on error
<!-- ##### FUNCTION quota_off ##### -->
<para>
Disables enforcing quotas on filesystems where quotas are configured.
</para>
@Returns: 0 on success, -1 on error
<!-- ##### FUNCTION quota_get_specials_user ##### -->
<para>
Gets a list of currently mounted filesystems which have user quotas enabled.
</para>
@Returns: If sucessful, a %NULL-terminated array of device names that should
be freed by quota_free_specials(). On error returns %NULL.
<!-- ##### FUNCTION quota_get_specials_group ##### -->
<para>
Gets a list of currently mounted filesystems which have group quotas enabled.
</para>
@Returns: If sucessful, a %NULL-terminated array of device names that should
be freed by quota_free_specials(). On error returns %NULL.
<!-- ##### FUNCTION quota_free_specials ##### -->
<para>
Frees the array returned by quota_get_specials_user() or
quota_get_specials_group()
</para>
@specials: array to be freed
<!-- ##### FUNCTION quota_get_user ##### -->
<para>
Gets information about user quota on a device.
