The ALIAS clause in a DECLARE LIBRARY statement block tells the program that you will use a different name than that used in the program. This only applies when declaring non-BASIC procedures.


Syntax

SUB pseudoname ALIAS actualname [(parameters)]


Parameters

  • The actual name is the same procedure name as it is inside of the DLL library.
  • The name does not have to be inside of quotes when using DECLARE LIBRARY.
  • In Qbasic ALIAS was originally only used in a DECLARE (non-BASIC statement) library statement declaration.


Example: Instead of creating a SUB with the Library statement inside of it, just rename it:

DECLARE LIBRARY SUB MouseMove ALIAS SDL_WarpMouse (BYVAL xoffset&, BYVAL yoffset&) END DECLARE

Explanation: When a Library procedure is used to represent another procedure name use ALIAS instead. Saves creating a SUB! Just place your name for the procedure first with the actual Library name after ALIAS.
