Title: argument question
Post by: Brian Alvarez on November 01, 2020, 10:37:34 PM

 Hello Charles, im trying to fix the associative array feature, so,
I have a class module that is supposed to return a string pointer. like this:

Code: [Select]

    function pStr(string k) as sys
        int i = this.getindex(k)
        return this.hBuffer + (i * 8)
    end function
When i use the class like this:

Code: [Select]

somefunction(byval asr.pStr("key"))
And try to print the value like this:

Code: [Select]

sub somefunction(string *a)
    print @a cr
    print a cr
end sub
 I get the address to a completely new variable that holds the address to the original string. What am i doing wrong?

As a reference... this returns a correct string:

Code: [Select]

    function cStr(string k) as string
        int i = this.getindex(k)
        static string *ps
        @ps = this.hBuffer + (i * 8)
        return ps
    end function

Hi Brian, double pointering '**' might help:

Code: [Select]

function fs(string**s) as string
print @s
return s
end function

string t="ok"
print @t 'same as '@s' inside function fs
print fs(t)
