← WoW API < setglobal

Always returns nil.

Details

As of the introduction of getfenv() into the API, setglobal() and getglobal() are somewhat superfluous. You can always do something along the lines of: 

 local globalenv = getfenv();
 local prevval = globalenv["MyVariable"];   -- "getglobal()"
 globalenv["MyVariable"] = 1234;            -- "setglobal()"
