然而,实际上在我们只想使用LUA_STRING这种类型的情况下,Lua脚本引擎会执行相应的类型转换,但Lua所做的从其它类型到字符串类型的转换的结果是C风格的单字节字符所组成的字符串串而不是我们所预期的双字节宽度的字符组成的字符串。 // concatenate multiple wide strings // const wchar_t *wcscat(wchar_t *wcharSt...

To concatenate strings, just use the .. operator: local space = " " app_name = "GLSL" .. space .. "Hacker" 3– Functions Functions in Lua can takemultiple argumentsand can returnmultiple results. function myKoolFunc(a, b, c)
New function "load", which loads Lua code progressively by calling a function to concatenate together data. New function "coroutine.running" which returns the currently-running coroutine, if any. New function "math.modf" which returns the integral and fractional part of a number. New maths funct...
The logging functions concatenate data more efficiently than operator .. does, so for best performance, do log:debug("Welcome ", first_name, ", thanks for visiting us ", time_of_day) rather than log:debug("Welcome " .. first_name .. ", thanks for visiting us " .. time_of_day) ...
