DESCRIPTION

Sys exports the UNIX system call numbers. The system call numbers are extracted from /usr/include/sys/syscall.h. System call numbers are given as first argument to SYSTEM.UNIXCALL. The array name contains the names of the system calls, e.g. name[4] = "write".

EXAMPLE

Implementation of the write(2) system call:

PROCEDURE Write(fd: SysTypes.File;
                buf: SysTypes.Address;
                cnt: SysTypes.Count) : SysTypes.Count;
   (* return value of    -1: I/O error
                        >=0: number of bytes written
   *)
   VAR
      d0, d1: INTEGER;
BEGIN
   IF SYSTEM.UNIXCALL(Sys.write, d0, d1, fd, buf, cnt) THEN
      RETURN d0
   ELSE
      SysErrors.Raise(d0, Sys.write, "");
      RETURN -1
   END;
END Write;

FILES

/usr/include/sys/syscall.h: system call numbers

BUGS

Not every system call described in chapter 2 of the UNIX manual is a unique system call, e.g. semsys realizes all semaphore operations.

Some of these system calls are not available on releases before Solaris 8.
