; Use a macro to make code a little cleaner.
|
|
; The parameter varname is optional.
|
|
; Syntax to use macro is :
|
|
; WANT equ expression
|
|
; USE func [,varname]
|
|
; If the 'varname' is defined, a table declaration is created like:
|
|
; GLOBAL TableName:DWORD
|
|
; Then, the table entry is created:
|
|
; If WANT is true, the table entry is created for the given function:
|
|
; varname DD func
|
|
; If WANT is not TRUE, a Not_Supported entry is put in the table:
|
|
; varname DD Not_Supported
|
|
; The resulting tables look like:
|
|
;
|
|
; GLOBAL ExampTable:DWORD
|
|
; ExampTable DD routine1
|
|
; DD routine2
|
|
; DD routine3
|
|
; ...
|
|
; Thus, each table is an array of function pointers.
