As a C programmer, I am a little confused whether need to check the return values of Lua C APIs.
For example, I know if "lua_pcall" returns non-zero value, it means failed. But as other non-void return
value functions, such as "lua_getglobal", doesn't it need to check the return value?
I try to refer the manual
, But the manual doesn't seem to give answers about whether need to check
the return values of APIs.
