Determines whether the given globally-accessible variable is secure. A variable in this context could be any of the basic lua types such as functions or userdata.
isSecure, taint = issecurevariable([table,] "variable")
- table? - table to check the the key in; if omitted, defaults to the globals table (
- string - string key to check the taint of. Numbers will be converted to a string; other types will throw an error.
- boolean - true if the
table[variable] key is secure, false if it is tainted.
- string? - name of the addon that tainted the table field; an empty string if tainted by a macro; nil if secure.
- Also returns
true, nil for keys that have never been used/defined, because nothing has tainted them yet.
table[variable] == nil, and table has a metatable with
__index, this function will return whether the metatable's
__index[varible] is tainted. You must remove the metatable to check whether
table[variable] itself is tainted.
- Cannot be used to check taint of local variables, or non-string table keys.
