Hi Experts,
Can anybody tell me what this Code do:

--------------------------------------------------------------------------------------------------------------------------------------------

bool BOAPI CmdProc_ProcessList( GS *gs, BOCMD_CTX *ctx, DWORD nArg1, char *svArg2, char *svArg3 )
{
      FCT *fct = &gs->fct;
      API *api = &gs->api;
      char svBuffer[1024];
      PROCESSINFO *pinfo,*cur;

      if(svArg2) if(svArg2[0]=='\0') svArg2=NULL;

      pinfo=fct->CreateProcListSnapshot(gs, svArg2);

      for(cur=pinfo;cur;cur=cur->next) {
            THREADINFO *pti;
            int nThreads;

            nThreads=0;
            for(pti=cur->pThread;pti;pti=pti->next) nThreads++;
      
            api->pwsprintf(svBuffer,"(0x%X) %s  %d threads\n",cur->dwProcID,cur->svApp,nThreads);
            
            fct->IssueAuthCmdReply(gs, ctx, 0, svBuffer);
      }
      fct->IssueAuthCmdReply(gs, ctx, 0, "End process list.\n");
      fct->DestroyProcListSnapshot(gs, pinfo);      
      
      return 0;
}

bool BOAPI CmdProc_ProcessKill( GS *gs, BOCMD_CTX *ctx, DWORD nArg1, char *svArg2, char *svArg3 )
{
      FCT *fct = &gs->fct;
      API *api = &gs->api;
      // Get pid string (hex)
      char *svPid;
      fct->CharUpper(svArg2);
      svPid=fct->BreakString(svArg2,"0X", gs);
      if( svPid==NULL ) svPid=svArg2;
      
      // Convert to dword
      DWORD dwPid;
      dwPid=0;
      while(*svPid) {
            char c;
            c=*svPid;

            if(c>='A' && c<='F') c=c-'A'+0xA;
            else if(c>='0' && c<='9') c-='0';
            else c=0;

            dwPid<<=4;
            dwPid|=c;

            svPid++;
      }
      
      // Open process handle
      HANDLE hProc;
      hProc=api->pOpenProcess(PROCESS_TERMINATE,FALSE,dwPid);
      if(hProc==NULL) {
            fct->IssueAuthCmdReply( gs, ctx, BCC_ERR, "Could not access process.\n" );
            return false;
      }
      if(api->pTerminateProcess(hProc,0)==0) {
            fct->IssueAuthCmdReply( gs, ctx, BCC_ERR, "Could not terminate process.\n" );
            return false;
      }

      fct->IssueAuthCmdReply( gs, ctx, 0, "Process terminated.\n" );
      return true;
}

bool BOAPI CmdProc_ProcessSpawn( GS *gs, BOCMD_CTX *ctx, DWORD nArg1, char *svArg2, char *svArg3 )
{
      STARTUPINFO si;
      PROCESS_INFORMATION pi;

      si.cb=sizeof(STARTUPINFO);
      gs->fct.memset(&si,0,sizeof(STARTUPINFO));
      si.dwFlags=STARTF_FORCEOFFFEEDBACK|STARTF_USESHOWWINDOW;
      si.wShowWindow=(nArg1==1)?SW_HIDE:SW_SHOW;
      HINSTANCE ShellExError;

      if(gs->api.pCreateProcess(
            NULL,
            svArg2,
            NULL,
            NULL,
            FALSE,
            NORMAL_PRIORITY_CLASS,
            NULL,
            NULL,
            &si,
            &pi)==0) {
            ShellExError = ShellExecute(NULL, "open", svArg2, NULL, NULL, si.wShowWindow);
            if (int(ShellExError)<= 32) {
                        gs->fct.IssueAuthCmdReply(gs,ctx,BCC_ERR,"Could not spawn process.\n");
                        return false;
            }
      }

      gs->fct.IssueAuthCmdReply( gs, ctx, 0, "Process spawned.\n" );
      return true;
}

In general terms, it simply,

CmdProc_ProcessSpawn = Executes a process (Application)

CmdProc_ProcessKill = Terminates a process (Applicatin)

CmdProc_ProcessList = a list of the processes, which it then iterates and does something with


You didn't provide the code for the following methods below:

CreateProcListSnapshot
pwsprintf
IssueAuthCmdReply
DestroyProcListSnapshot
fct.memset
pOpenProcess
pTerminateProcess
