Who here has a Youtube-DL compile for WinXP?

[user57]

i looked at it in doxygen QueryWorkingSet and Ex are doing partly the same thing
they call up  NtQueryVirtualMemory

where then both access the either "MemoryWorkingSetList" or "MemoryWorkingSetListEx" as parameter
//
typedef enum _MEMORY_INFORMATION_CLASS
{
    MemoryBasicInformation,
    MemoryWorkingSetList,       // <-- this 
    MemorySectionName,
    MemoryBasicVlmInformation,
    MemoryWorkingSetExList  // <-- and this
} MEMORY_INFORMATION_CLASS;
 

however on msdn they might look different:
(QueryWorkingSet)
typedef struct _PSAPI_WORKING_SET_INFORMATION {
  ULONG_PTR               NumberOfEntries;
  PSAPI_WORKING_SET_BLOCK WorkingSetInfo[1];
} PSAPI_WORKING_SET_INFORMATION, *PPSAPI_WORKING_SET_INFORMATION;

(QueryWorkingSetEx)
typedef struct _PSAPI_WORKING_SET_EX_INFORMATION {
  PVOID                      VirtualAddress;
  PSAPI_WORKING_SET_EX_BLOCK VirtualAttributes;
} PSAPI_WORKING_SET_EX_INFORMATION, *PPSAPI_WORKING_SET_EX_INFORMATION;

the parameter sizes are the same, so a linking to that function works, just maybe not fully functional
that we should keep an eye on if it behave different

if they behave different you have have to write a code that redirects to QueryWorkingSetEx to -> NtQueryVirtualMemory with that MemoryWorkingSetExList
xp might got this function parameter
