 Linux system calls take arguments as follows :

   i386    m68k    ppc
   %eax    %d0     r0      System call number
   %ebx    %d1     r3      first argument
   %ecx    %d2     r4      second argument
   %edx    %d3     r5      third argumens
   %esi    %d3     r6      fourth argument
   %edi    %d4     r7      fifth argument

  That is why we define a special type, with only these arguments
  To make it processor independent, we don't give any system dependent
  names, but the rather abstract reg1,reg2 etc;

  SysCallRegs=record
    reg1,reg2,reg3,reg4,reg5,reg6 : longint;
  end;
  PSysCallRegs=^SysCallRegs;
  TSysCallRegs=SysCallRegs;

  dirent = packed record
    ino,
    off    : longint;

    name   : array [0..255] of char;
  end;
  pdirent =^dirent;
  TDirEnt = dirent;

  TDir = packed record
    fd     : integer;
    loc    : longint;
    size   : integer;
    buf    : pdirent;
  {The following are used in libc, but NOT in the linux kernel sources ??}
    nextoff: longint;
    dd_max : integer; {size of buf. Irrelevant, as buf is of type dirent}
    lock   : pointer;
  end;

  $Log$
  Revision 1.12  2003-09-14 20:15:01  marco
   * Unix reform stage two. Remove all calls from Unix that exist in Baseunix.

  Revision 1.11  2003/08/21 22:24:52  olle
    - removed parameter from fpc_iocheck

  Revision 1.10  2003/07/08 21:23:24  peter
    * sparc fixes

  Revision 1.9  2003/07/08 14:18:40  peter
    * fdset changed to 1024 bits

  Revision 1.8  2003/05/15 22:50:50  jonas
    * the stat type is processor-dependent
    * the dev_t tpye is processor dependent. Don't use it in the stat type
      however, as that one is also used at a time where dev_t is already
      defined as qword

  Revision 1.7  2002/09/07 16:01:20  peter
    * old logs removed and tabs fixed

  Revision 1.6  2002/07/29 17:50:02  florian
    + added register location description for ppc
