How can I print the data contained by a C++ Map while debugging using DBX

Question

I want to know the contents of a Map while debugging a c++ program. I am using command line dbx.

I have pointer to the map.

Is there a way in which i can get the data printed.

--

Edit: p *dataMap will give me this::

 p *dataMap
*dataMap = {
    __t = {
        __buffer_size   = 32U
        __buffer_list   = {
            __data_ = 0x3ba2b8
        }
        __free_list     = (nil)
        __next_avail    = 0x474660
        __last          = 0x474840
        __header        = 0x3b97b8
        __node_count    = 76U
        __insert_always = false
        __key_compare   = {
/* try using "print -r" to see any inherited members */
        }
    }
}

Thanks

I generally debug C using DBX. Doesn't `print *ptr` work for you? — Pavan Manjunath, Mar 27 '12 at 06:24
`__next_avail`, `__header` are pointers and you want to see their contents? — Pavan Manjunath, Mar 27 '12 at 07:01
No, basically what i want is that I can access the key and values pair of the map. Can there be some way? — Kumar Alok, Mar 28 '12 at 06:29

you need to write a ksh function to pretty print map, here is an example :

put following line in .dbxrc

source /ksh_STL_map

in dbx, use ppp to call ksh function that define in ksh_STL_map:

(dbx) ppp k

k = 2 elems {343, 0x301f8; 565, 0x30208}

I tried to post content of ksh_STL_map here, but this editor format will mess up the content, it's better that you post your email, then I can send ksh_STL_map directly to you.

@chichin ko: Hey can you please mail the function to me, or put it here. – Kumar Alok Apr 10 '12 at 09:21
Kumar: I just send ksh_STL_map to you via email – chihin ko Apr 12 '12 at 00:54
can we not post emails and post the code here for others? – Jason Sep 11 '19 at 15:11
