/**
@file forge.h An API for constructing LV2 atoms.
- This file provides a simple API which can be used to create complex nested
- atoms by calling the provided functions to append atoms (or atom headers) in
- the correct order.
+ This file provides an API for constructing Atoms which makes it relatively
+ simple to build nested atoms of arbitrary complexity without requiring
+ dynamic memory allocation.
- The size of containers is automatically handled to any depth. All functions
- that start a container take a pointer to an uninitialised stack frame which
- will be initialised and must be popped when the container is finished.
+ The API is based on successively appending the appropriate pieces to build a
+ complete Atom. The size of containers is automatically updated. Functions
+ that begin a container return (via their frame argument) a stack frame which
+ must be popped when the container is finished.
- All output is written to a user-provided buffer, or sink function. Thus,
- this API can be used to create atoms on the stack, on the heap, in LV2 port
- buffers, or in a ringbuffer.
+ All output is written to a user-provided buffer or sink function. This
+ makes it popssible to create create atoms on the stack, on the heap, in LV2
+ port buffers, in a ringbuffer, or elsewhere, all using the same API.
This entire API is realtime safe if used with a buffer or a realtime safe
- sink, except lv2_atom_forge_init(), which is only realtime safe if the URI
+ sink, except lv2_atom_forge_init() which is only realtime safe if the URI
map function is.
Note these functions are all static inline, do not take their address.
