pub type svn_tristate_t = c_uint;Expand description
Generic three-state property to represent an unknown value for values that are just like booleans. The values have been set deliberately to make tristates disjoint from #svn_boolean_t.
@note It is unsafe to use apr_pcalloc() to allocate these, since ‘0’ is not a valid value.
@since New in 1.7.
