    I would like to view the entire contents of an array (1D) and matrix (2D) using the debugger in XCode - lldb.
    I created these array/matrices using pointers and malloc(). The debugger shows the first element of the array/matrix, how do I view the entire contents of these arrays/matrices.
    Thanks for any help.

    I don't have a Mac in front of me at the moment to try it. But I know the 'gdb' command to dump the information. 'lldb' is probably similar.


    x/5i ptr
    That would dump memory at pointer 'ptr' with 5 integers. You can replace the 5 with whatever count you want. You can replace the 'i' with other units like 'u' unsigned, 'x' hex, etc.

    Thanks, I'll try that, and I'll let you know how it works out.
