Returning strings from a function

[MushroomHead]

Code (glbasic) Select Expand


b$ = test2()
PRINT b$, 100, 100
SHOWSCREEN
MOUSEWAIT
END

FUNCTION test2:
LOCAL a$
a$ = "HelloWorld"
RETURN a$
ENDFUNCTION


Why doesn't this work?

[Kitty Hello]

FUNCTION test2$:

[MushroomHead]

Thanks, one other question, when exporting strings as a DLL is this correct?

Code (glbasic) Select Expand


EXPORT test2$

FUNCTION test2$:
LOCAL a$
a$ = "HelloWorld"
RETURN a$
ENDFUNCTION


Is this right? When dumping the DLL I get a function called test2_Str but when I call this function I get a crash. How are strings returned i.e. are they like "C" strings with a null "\0" terminator?

This is how I call it in powerbasic :-

Code (glbasic) Select Expand


DECLARE FUNCTION test2 CDECL LIB "test.dll" ALIAS "test2_Str" () AS STRING

FUNCTION PBMAIN () AS LONG
    MSGBOX test2()
END FUNCTION
