5.2 luaL_execresult and luaL_fileresult

[liam mail <liam.list@...>]

Maybe I am missing something yet both of these functions seems to be lacking any sort of meaningful documentation[1][2] which explains the purpose and usage of them.

Looking at the documentation that is written for these two functions[3] makes them sound like they are actually internal functions for which I do not see the purpose of them. ie why would the C API have functions to generate return values for Lua calls and how would you use them? 

I really do not know so any enlightenment would be gratefully received.

luaL_fileresult

This function produces the return values for file-related functions in the standard library (io.open, os.rename, file:seek, etc.).

luaL_execresult

This function produces the return values for process-related functions in the standard library (os.execute and io.close).
