@ -159,8 +159,13 @@ typedef bool (*HPredicate)(HParseResult *p, void* user_data);
* Type of a parser that depends on the result of a previous parser,
* used in h_bind(). The void* argument is passed through from h_bind() and can
* be used to arbitrarily parameterize the function further.
*
* The HAllocator* argument gives access to temporary memory and is to be used
* for any allocations inside the function. Specifically, construction of any
* HParsers should use the '__m' combinator variants with the given allocator.
* Anything allocated thus will be freed by 'h_bind'.
