 WinDbg : Parsing Arrays In The Debugger


Many a times data structs like arrays need parsing in windbg. These don't lend themselves as well as the LIST_ENTRY based structs do, because the debugger can parse such lists. Here are 2 simple ways of parsing arrays.  
 
typedef struct _RECORD
{
    ULONG Foo;
    ULONG Bar;
} RECORD;

typedef struct _STATE
{
    RECORD Records[100];
} STATE;

int main()
{
    STATE localXyz;
}
Commands used:
  1. for
  2. dx
1: kd>.for (r @$t0 = 0; @$t0 < @@(#RTL_NUMBER_OF(localXyz.Records)); r @$t0 = @$t0 + 1) { ?? localXyz.Records[@$t0] }   struct _RECORD    +0x000 Foo          :     +0x004 Bar        :    There is another way of doing this in the latest version of Windbg, and that is using the dx command.

1: kd>dx -r2 -g localXyz.Records

  Note : This example uses stack based objects, and hence uses the dot operator in the commands, however, if you are using a pointer to the struct you want to display, you will have to use the arrow operator instead of the dot.
