AW: Debug Infos von TCriticalSection beim compilen von FPC Application

  Alt 28. Okt 2022, 16:07
Falls du damit die InitializeCriticalSectionEx Methode meinst, dann hätte ich hier vielleicht etwas für dich.

Code:
unit CriticalSectionEx;

{$IFDEF FPC}
  {$mode ObjFPC}{$H+}
{$ENDIF}

interface

uses
  Classes, SysUtils, syncobjs;

  function InitializeCriticalSectionEx(var cs: TRTLCriticalSection;
                                       dwSpinCount, Flags: DWORD): Boolean;
                                       stdcall; external 'kernel32.dll';
type

  { TCriticalSectionEx }

  TCriticalSectionEx = class(TSynchroObject)
  protected
    FCriticalSection: TRTLCriticalSection;
  public
    procedure Acquire;override;
    procedure Release;override;
    procedure Enter;
    function TryEnter:boolean;
    procedure Leave;
    constructor Create; overload;
    constructor Create(ASpinCount, AFlags: DWORD); overload;
    destructor Destroy;override;
  end;

const
  // -> from winnt.h
  // These flags define the upper byte of the critical section SpinCount field
  //
  //#define RTL_CRITICAL_SECTION_FLAG_NO_DEBUG_INFO        0x01000000
  RTL_CRITICAL_SECTION_FLAG_NO_DEBUG_INFO =                $01000000;
  //#define RTL_CRITICAL_SECTION_FLAG_DYNAMIC_SPIN         0x02000000
  RTL_CRITICAL_SECTION_FLAG_DYNAMIC_SPIN =                 $02000000;
  //#define RTL_CRITICAL_SECTION_FLAG_STATIC_INIT          0x04000000
  RTL_CRITICAL_SECTION_FLAG_STATIC_INIT =                  $04000000;
  //#define RTL_CRITICAL_SECTION_FLAG_RESOURCE_TYPE        0x08000000
  RTL_CRITICAL_SECTION_FLAG_RESOURCE_TYPE =                $08000000;
  //#define RTL_CRITICAL_SECTION_FLAG_FORCE_DEBUG_INFO     0x10000000
  RTL_CRITICAL_SECTION_FLAG_FORCE_DEBUG_INFO =             $10000000;
  //#define RTL_CRITICAL_SECTION_ALL_FLAG_BITS             0xFF000000
  RTL_CRITICAL_SECTION_ALL_FLAG_BITS =                     $FF000000;

  DEFAULT_SPIN_COUNT = 4000;


implementation


{ TCriticalSectionEx }

procedure TCriticalSectionEx.Acquire;
begin
  EnterCriticalSection(FCriticalSection);
end;

procedure TCriticalSectionEx.Release;
begin
  LeaveCriticalSection(FCriticalSection);
end;

procedure TCriticalSectionEx.Enter;
begin
  Acquire;
end;

function TCriticalSectionEx.TryEnter: boolean;
begin
  result := TryEnterCriticalSection(FCriticalSection) <> 0;
end;

procedure TCriticalSectionEx.Leave;
begin
  Release;
end;

constructor TCriticalSectionEx.Create;
begin
  inherited Create;
  InitializeCriticalSectionEx(FCriticalSection, DEFAULT_SPIN_COUNT, 0);
end;

constructor TCriticalSectionEx.Create(ASpinCount, AFlags: DWORD);
begin
  InitializeCriticalSectionEx(FCriticalSection, ASpinCount, AFlags);
end;

destructor TCriticalSectionEx.Destroy;
begin
  inherited Destroy;
end;

end.
Könnte es aber sein das du versuchst in eine CriticalSection zu Entern und diese fehl schlägt ?
Vielleicht reicht es auch einfach den Eintritt mit der TryEnter Methode zu versuchen.

Ein neuer Tag bringt so einiges mit sich. Was auch immer es ist, es bleibt ein kleines Abenteuer.
