equivalent setpgrp() in lazarus

[marcov]

And ASCII was introduced by IBM.

I don't care who introduced it: it's supported by Linux and that manpage cites POSIX.1 (with non-standard variations for SysV and BSD).

But not for that call afaik. For other calls on that manpage.

Hmmm. man setpgrp ->

DESCRIPTION
       All  of these interfaces are available on Linux, and are used for getting and setting the process group ID (PGID) of a process.  The
       preferred, POSIX.1-specified ways of doing this are: getpgrp(void), for retrieving the calling process's PGID;  and  setpgid(),  for
       setting a process's PGID.

and

The System V-style setpgrp(), which takes no arguments, is equivalent to setpgid(0, 0).

       The BSD-specific setpgrp() call, which takes arguments pid and pgid, is a wrapper function that calls

           setpgid(pid, pgid)

       Since glibc 2.19, the BSD-specific setpgrp() function is no longer  exposed  by  <unistd.h>;  calls  should  be  replaced  with  the
       setpgid() call shown above.

Also in ./rtl/linux/x86_64/sysnr.inc:

Code: Pascal  [Select][+][-]

1.   syscall_nr_setpgid                           = 109;
2.   syscall_nr_getppid                           = 110;
3.   syscall_nr_getpgrp                           = 111;
4. ...
5.   syscall_nr_getpgid                           = 121;
6.  

It looks as though the Netware RTL is the only one to implement FpSetpgid(), which might in practice be what OP's looking for.

From my debian manpage:

POSIX.1-2001 also specifies getpgid() and the version of setpgrp() that takes no arguments.  (POSIX.1-2008 marks  this  setpgrp()
       specification as obsolete.)

       The  version of getpgrp() with one argument and the version of setpgrp() that takes two arguments derive from 4.2BSD, and are not
       specified by POSIX.1.

So no parameter version of setpgrp was shortly specified and then obsoleted, and the 2 argument version (which this thread is about) never was standarized

I don't think OP specifies the number of parameters. In any event, there appear to be Linux syscalls that can't be easily accessed other than by going via the termios stuff (which, TBH, is probably functionally adequate).

Yes. Correct. Grep will tell you so too... (I am repeating myself).

Yes, I found it via grep. But what he /should/ be looking for is setpgid(), which is unimplemented.

That should be fpsetpgid()...

Agreed, from the POV of FPC naming.
