Purpose |
Obtain a 32-bit address of a label, Sub, Function, or Fastproc. |
Syntax |
AddrVar = CODEPTR(Label) AddrVar = CODEPTR(ProcName) |
Remarks |
CODEPTR retrieves the address of a Label, Sub, Function, or FastProc. The first form may be used to get the address of a label located within the same procedure. The second form is used to obtain the address of a Sub, Function, or FastProc. CODEPTR is particularly useful when it is necessary to pass the address of a SUB or FUNCTION to PowerBASIC or Windows to specify a Callback Function. |
Restrictions |
CODEPTR cannot obtain the address of a METHOD or PROPERTY as direct access to them would constitute an illegal operation. |
