38.9 Tree-sitter C API Correspondence

Emacs’s tree-sitter integration doesn’t expose every feature provided by tree-sitter’s C API. Missing features include:

In addition, Emacs makes some changes to the C API to make the API more convenient and idiomatic:

Below is the correspondence between all C API functions and their ELisp counterparts. Sometimes one ELisp function corresponds to multiple C functions, and many C functions don’t have an ELisp counterpart.
