How to print the contents of a memory address using LLDB?

Question

I am using LLDB and wondering how to print the contents of a specific memory address, for example 0xb0987654.

Here's a simple trick for displaying typed arrays of fixed-length in lldb. If your program contains a long* variable that points to 9 elements, you can declare a struct type that contains a fixed array of 9 long values and cast the pointer to that type:

long *values = new long[9]{...};

(lldb) expr typedef struct { long values[9]; } l9; *(l9 *)values
(l9) $1 = {
  values = {
    [0] = 0
    [1] = 1
    [2] = 4
    [3] = 9
    [4] = 16
    [5] = 25
    [6] = 36
    [7] = 49
    [8] = 64
  }
}

I use the typedef when I'm coding in C, it's not needed in C++.
