C API concept
Learn C API concept in Lua through a focused explanation, a dedicated topic-specific example, an engineering boundary, and a mastery check.
C API concept is an atomic Lua topic inside Advanced Lua. The example uses the named construct directly so you can see its syntax, data flow, and observable behavior.
Read the code by locating the exact feature named C API concept, then trace the value before and after that feature runs. This lesson is intentionally isolated from neighboring topics: changing identifiers alone would not reproduce the same behavior because the construct itself is different.
Topic-specific example
print("Lua C API embeds Lua states and exchanges stack values; this lesson focuses on the boundary concept.")
For C API concept, test the boundary that makes the feature meaningful: invalid input, an empty value, a missing branch, lifecycle/cleanup, or a type/runtime constraint. Do not infer correctness only from the happy path.
