C Structure holding a pointer to another structure how access member of that inner structure pointer

Question

The structure looks like this

typedef struct _PROCESS_INFORMATION {
  HANDLE hProcess;
  HANDLE hThread;
  DWORD  dwProcessId;
  DWORD  dwThreadId;
} PROCESS_INFORMATION, *LPPROCESS_INFORMATION;


struct PLAYER
{
  /* 0x0/0 */ struct PROCESS_INFORMATION *ProcessInformation;
  /* 0x4/4 */ unsigned long dword4;
  /* 0x8/8 */ unsigned long dword8;
  /* 0xC/12 */ unsigned long dwordC;
  //... Lots of fields here
}

Here is the prototype for TerminateProcess

BOOL WINAPI TerminateProcess(
  _In_  HANDLE hProcess,
  _In_  UINT uExitCode
);

I tried all 3 of these below and failed.

unsigned int v102; //exit code.
struct PLAYER *player; // eax@9

TerminateProcess(player->ProcessInformation->hProcess, v102);
TerminateProcess(player->ProcessInformation.hProcess, v102);
TerminateProcess(*(player->ProcessInformation)->hProcess, v102);

The arrow -> works for other members of the PLAYER struct pointer but if the member inside the struct PLAYER is a pointer to another struct then I get compiler problems.

All 3 above give me the compiler problems.

Maybe I had to use *LPPROCESS_INFORMATION inside the struct PLAYER or maybe I had to use struct _PROCESS_INFORMATION * because I really hate using typedef's

(yeah I just started using C only a week ago I usually code in Java/C#/VB.NET so this is all new to me.)

Edit: Seems I found the problem I was using a stupid typedef no wonder I had so much problems.. Those typedef's eliminate the use for a type which in this case is a struct so my structure was very screwed up..

Fix was to replace

/* 0x0/0 */ struct PROCESS_INFORMATION *ProcessInformation;

with

/* 0x0/0 */ struct _PROCESS_INFORMATION *ProcessInformation;

Now I can use the beautifiul arrows non-stop

player->ProcessInformation->hProcess

Is this right?

Answer 1

player->ProcessInformation->hProcess 

is correct. Good luck!
