[SOLVED] How do I print a 1d array in gdb and show all the elements...

trist007 · 11-08-2012, 09:24 AM

Here is what I have tried so far.

Code:

(gdb) print *cache_array@1024
$10 = {0, 0, 0, 241426, 16432, 241506, 241013, 241479, 241506, 241013, 241426, 241479, 241506, 241427, 241013, 241479, 
  241013, 16432, 241479, 241506, 241506, 241260, 16432, 16432, 241426, 240850, 241124, 241249, 241506, 241251, 16432, 
  241249, 241251, 16432, 241249, 241506, 240850, 241124, 241495, 241249, 16432, 240850, 241124, 241249, 240850, 241249, 
  16432, 241506, 241495, 16432, 241491, 241506, 241495, 16432, 241506, 241239, 241425, 241239, 376817, 241506, 241251, 
  241425, 376817, 376817, 241506, 16435, 16434, 376817, 241429, 241251, 16435, 241429, 241506, 241491, 241425, 241238, 
  241425, 241506, 376817, 241238, 241506, 376817, 16435, 241491, 16435, 16432, 241255, 241506, 241255, 241491, 16432, 
  241506, 16432, 241257, 241506, 241251, 16432, 241506, 241426, 241506, 241426, 16432, 241251, 241506, 16432, 241401, 
  241506, 241426, 241251, 16435, 16432, 241491, 241506, 241260, 241251, 376817, 16432, 241252, 241506, 376817, 376817, 
  241256, 241253, 241252, 241253, 241481, 241260, 241256, 16437, 241251, 241506, 241426, 16437, 16432, 241506, 241426, 
  241426, 16437, 16432, 241506, 241481, 16437, 241426, 241506, 16437, 16435, 241426, 241506, 16434, 241506, 16437, 241426, 
  16437, 16420, 241471, 241506, 16437, 16420, 241471, 241426, 241506, 16432, 16420, 241426, 16432, 16420, 241506, 241426, 
  16420, 241506, 241426, 16437, 241506, 376817, 241426, 376817, 241506, 241426, 16437, 241426, 16420, 16437, 241506, 376817, 
  241260, 241506, 376817, 241506, 376817, 241426, 16431, 241506, 376817, 241426, 16431, 393214, 16420, 241258, 16431, 
  393214...}

But it only prints about 160 of them instead of 1024, which is the number of elements in the array. How do I print them all? I'm thinking there's a string limit, which is why there is an "..." at the end. How do I increase that?

I thought about it more, and now I know why.

Nevermind got it. The help function in GDB is quite good.

set print elements 2048

You can print 1 element per line with
set print array on

Or disable it if it's not your bag
set print array off

Actually another question. On my first post, notice the first 3 elements are 0s. Why is that?
