c++ dll returning string

[Muk108]

i have no idea how to return a string from my dll here is some code i have so far

main.cpp

char *__stdcall myfunction(char * variable)
{
return variable;
}


main.def


EXPORTS
myfunction


vb code


Private Declare Function myfunction Lib "my.dll" (ByVal variable As String) As String
-----
MsgBox myfunction("test")


whats wrong i get a message saying it cant read the memory and also one that says it cant write to the memory... thanks for the help.
