This section details all Lua functions. Functions are ordered alphabetically by name.


Many Lua functions act as wrappers for C code which means that the calling code needs to take steps to ensure safety. When calling a C API, make sure that all the arguments are valid as an unexpected nil may crash the system or have other undesirable results. Additionally, the data structures returned from C APIs are often shared between C and Lua. The most important consequence of this is that arrays coming from C APIs must only be accessed with existing indices, as opposed to Lua which simply returns nil on out-of-bounds access. Failure to do this on a Lua table connected to a C array will cause the system to fail.
