[fpc-devel]Linux RTL: getitimer / setitimer

[Judison]

Hi all,

I can't find getitimer and setitimer in linux RTL, (present in BSD rtl)
How can I use this in my project?

I try'ed this code below, but it does not compile, how do I to use SysCall and SysCallRegs ?

TIA,
Your friend,
Judison


{$PACKRECORDS C}
type
 TTimeVal = record
   tv_sec: longint;
   tv_usec: longint;
 end;

 TITimerVal = record
   interval: TTimeVal;
   value: TTimeVal;
 end;

const
  ITimer_Real    = 0;
  ITimer_Virtual = 1;
  ITimer_Prof    = 2;


// int getitimer(int which, struct itimerval *value);
// int setitimer(int which, const struct itimerval *value, struct itimerval *ovalue);

function getitimer(which: longint; var value: TITimerVal): longint;
var
  regs: SysCallregs;
begin
  regs.reg2:=which;
  regs.reg3:=longint(@value);
  Result := SysCall(SysCall_nr_getitimer,regs);
end;

function setitimer(which: longint; const value: TITimerVal; var ovalue: TITimerVal): longint;
var
  regs: SysCallregs;
begin
  regs.reg2:=which;
  regs.reg3:=longint(@value);
  regs.reg4:=longint(@ovalue);
  Result := SysCall(SysCall_nr_setitimer,regs);
end;
